10 significant steps for an effective cloud migration

Moving your IT infrastructure to the cloud has become a business necessity for many organizations. However, the plethora of cloud providers and complex cloud migration challenges can be intimidating to organizations stuck with legacy applications and an on-premises setup for their enterprise systems. In this blog post, we will describe the 10-steps that you must undertake for a successful cloud adoption.

1) Decide the objectives of migrating to the cloud

This is the most important step in the process. You must analyze if its reduction in cost, competitors in the market or security for your IT infrastructure that is behind your motivation for cloud migration.

Cloud migration is significant for attaining real-time efficient performance and competence. That is why the cloud migration strategy necessitates cautious analysis, preparation, and implementation to guarantee the compatibility of the cloud solution with structural necessities. This step of charting your aims will support everybody in the team to comprehend the idea of migration and to understand its benefits for the organization.

2) Analyze the expected outcomes

When you’ve finally made up the decision of moving to the cloud, you must do an analysis of the advantages and drawbacks. This is because of the fact that cloud migration enhances the operations if done right but it may turn out to be troublesome if not done right. SWOT (Strengths, Weaknesses, Opportunities, and Threats) analysis is the best way to figure this out. Perform this analysis and list the derived outcomes.

3) Evaluate your environment

Before initiating the process, you should make a detailed valuation of your present condition like applications to be migrated and present infrastructure-for prices and resources. This is essential as it will be the basis for determining the further steps to be taken in the process of migration.

A few points you should evaluate:

List the applications to be migrated

Audit your current infrastructure

Understand current cost and resource levels

4) Determine your deployment model

As per your requirements, you can choose among the following methods of “aaS” (as a Service):

Infrastructure as a Service (IaaS): This allows the user to control all hardware and software via the cloud.

Platform as a Service (PaaS): This supplements features of development to IaaS features.

Software as a Service (SaaS): This is simple as compared to IaaS or PaaS, and is most effective for smaller establishments.

5) Select the right cloud partner

It is very important to choose the right cloud partner. While doing the same, you must consider looking at the partner’s past practices of working on projects similar to yours. It would be better if you could find partners who have worked with clients that are similar in size and belong to the same industry as yours.

Microsoft Azure, Amazon Web Services, and other cloud providers provide certifications. Choosing a certified partner can make the difference between an effective cloud migration and an unfortunate setback.

6) Types of cloud environment to choose

Here are the three elementary cloud types for web hosting and their main features:

The public cloud – it is nearly equal to a common offsite server.

Convenient to use

Cost-effective as it is a pay-per-use model

Run by a third party at a remote location

Flexible and highly scalable

Geo-redundancy

The private cloud – it gives a single occupant solution to a company.

Company-specific

Better control and reliability

Can be customized

Company incurs maintenance cost

Needs internal IT proficiency

The hybrid cloud – it is a mix of the above two.

Hypervisor and cloud software layers needed

Ideal for dynamic workloads

Cloud bursting is possible

7) Define the architecture

After selecting the type of cloud the next step is to define the architecture required for the migration. Make a list of the apps that you’ll migrate. As per the analysis that was done in step 3 (Evaluate your present condition), define the constituents that you’ll require. Consider the storage requirements and computing power etc.

Since the traditional and cloud apps do not port well into each other all the time, there are chances that they may not give the best out of them, even if they are ported. In order to avoid difficulties in the future, you must check if your hosting requires outsourced cluster equivalents, load balancers, or database replication.

8) Choose the right cloud provider

Next step is to select the cloud provider that will fulfill all the requirements. Look at all the factors while selecting the provider. Don’t forget to consider the assured SLA, quick customer service, better feedback, etc.

9) Deployment

By the time you reach this step you have prepared almost everything, and you are ready for the migration process. Now you’ve to plan how to do it. Following are the points to be taken under consideration here:

Nominal interruption time

Sequence of migration of applications

Time limit and constant monitoring for a successful migration

Alterations in end-user processes

Preparation requirements

10) Execute the plan and monitor the implementation

Execution is the most crucial step. Make sure that you perform this real challenge with cautions. Begin with a double check on planning, timing, and strategy.

Here are the steps you need to follow for a successful execution:

Data backup – Before migration, you must back up the present servers and data. This would ensure that no information will be lost. Store your data safely and make sure that it can be easily retrieved.

Deployment – Set up the cloud environment. Do the provisioning, connections, and testing of all the individual constituents separately.

Migration of the data – Post-deployment, migrate the present data to the cloud. This process will take time and may require some changes to fit. Test all the connections and ensure that they are working appropriately.

Testing – This final step is very important. Do the testing and rectify errors, if any. After migration of all the data, check that everything is working as estimated. Double check the presence and safety of the data in the environment. You must test it so that the end users do not face any issues while using the app and if any corrections are required, they should be done easily as a part of this testing.

Monitor the implementation – Implement monitoring after successful migration. You should get notifications if any issue arises with the cloud environment to get it fixed in time.

Additional things that you must keep a check on:

1. For an appropriate cloud hosting, scalability is a must. The application that is required to get scaled must be positioned on a load balancer so that it can respond in real-time whenever there is an increased necessity for means. If you are selecting IaaS as your infrastructure, you’ll have to check if the service provider charges extra for this feature. PaaS solutions have a built in scalability to some extent. However, the company providing the infrastructure decides the total cost.

2. For every monitoring, computing and storing system, proper security is necessary. The cloud providers take care for security concerns like avoiding unnecessary traffic outside a particular range from accessing the machines on which your data is stored. They also assure that automatic security updates are applied to their systems to safeguard your data from being susceptible to the latest known security threats. By storing your data in the cloud, you can access it from any device, and make changes remotely.

3. For any assistance, good customer service is needed. You must check if your hosting company assures a certain level of uptime or not. This is because after moving the data and customer-facing applications into the cloud, if you still face downtime, it would result in a huge setback. So, the hosting company must guarantee that this will not happen. You must figure out the automated maintenance schedule, and confirm appropriate and in-time security and software build updates.

4. Coordinate with your cloud provider to stay in agreement with municipalities and software company licenses. When you make your business global, laws in diverse jurisdictions must be followed.

Why enterprises need to adopt a multi-cloud strategy

Multi-cloud is the next big thing today that is offering businesses the capability to experience multiple cloud services and build the best infrastructure. Companies now do not need to move between platforms because with a multi-cloud adoption strategy you can bring many technologies together such as AWS, Azure, VMware and more in one system to efficiently meet their business goals. One of the prime reasons why enterprises prefer this approach is to avoid depending on just one cloud vendor for all their cloud-related needs.

“81% of enterprises have a multi-cloud strategy” – 2018 State of the Cloud Survey, RightScale

There are many types of multi-cloud architectures including re-deployment, cloudification, relocation, refactoring, rebinding, replacement, and modernization for organizations to adopt.

Multi-cloud rebinding

A multi-cloud rebinding is an architecture that is used to route users to the nearest data center when your primary cloud or on-premises data center fails. Basically, this architecture can configure and monitor the status of the service to which they are directing the users, and if the service is not available, it helps to route traffic to another resource.

Let’s see how an application is deployed in a multi-cloud setting:

Figure 1: Multi-cloud rebinding architecture diagram

In this architecture diagram, a re-architected application is deployed partially on multiple cloud environments. Here, AC1 and AC2 are two application components hosted on-premises before migration. As both the components are independent integrity units, AC1 remains on-premises while two AC2s are deployed on AWS and Azure for disaster recovery.

Benefits of adopting a multi-cloud solution

1. Ability to mix different delivery models

Multi-cloud allows you to choose from a growing range of services to create a customized solution that best suits your organization. You gain the ability to use mixed delivery models including SaaS (Software-as-a-Service), PaaS (Platform-as-a-Service), and IaaS (Infrastructure-as-a-Service). As well as increase the capability for each existing and new applications and make the decision that best suits your business goals. You can use a combination of platforms including Amazon Web Services(AWS), Azure, Google Cloud Platform, VMware and more. This multi-cloud architecture becomes your base for new business capabilities and functions.

2. Making data management flexible

Many organizations require using different types of data depending on their industry. Multi-cloud can be the best fit for such organization as they require storing data in particular type of cloud while running other workloads in another cloud. When you manage data on multiple clouds, you can be confident that your data will remain available and secure even if one of the cloud hosts fail. For example, an e-commerce business may require hosting data on multiple cloud platforms that best supports digital media such as images, videos, animation, graphics, and more.

Multi-cloud also offers low latency and allows quick data transfer across different platforms, and manages your workloads and services, as it utilizes more than one cloud services, ensuring that your enterprise serves customers without any inconvenience.

Cloud strategy and assessment workshop The adoption of cloud-based infrastructure by enterprises is increasing greatly. However, a lot of enterprises are still reluctant to adopt a cloud strategy due to lack of skills or knowledge. Download

3. Avoiding single vendor lock-in

Initially, single cloud vendors led enterprises for a lock-in period that often results in limited flexibility, prolonged proof of concepts, delayed decisions, and costlier outcomes. Such issues would further result in slowing down the business operations and overall fail the organization to meet their business-changing needs timely.

Multi-cloud deployment allows you to get full control over your systems including the power to switch your cloud platforms easily. When you use a mix of private and public cloud platforms, you will be able to match your system needs to your business solutions. With multi-cloud, you can scale down your cloud services to the local server whenever desired and without causing disruptions to your business operations. Such ability will reduce dependency over a single vendor and open the doors to negotiation for favorable agreements.

4. Optimizing cost-effective outcomes

The traditional delivery methods of cloud platform and the scaling efficiencies of multiple cloud services can always be compared. With multi-cloud strategy, you can use your own apps anytime into the cloud and build greater resiliency at a lower price than the previous redundancies would have costed you. You can easily share your workloads across multiple cloud platforms and reduce downtime simultaneously.

Multi-cloud proves to be a cost-effective solution, as enterprises get to analyze and reduce capital expenses related to hardware, server, and systems that have an impact on their business performance and productivity. In short, the multi-cloud solution enables you to scale cloud services at dropping costs – without disrupting your business operations.

5. Added security with multi-cloud

Multi-cloud allows a combination of a private or public cloud platform. For added security, it is advisable that you secure your data in the private cloud while operating other areas of the business using a public or hybrid cloud environment.

Using a multi-cloud architecture will also help you a lower risk of a DDoS (distributed denial-of-service) attack by providing a level of resiliency, which is not possible with a single provider. A DDoS attack is a serious result of several computer systems attacking a server, a website, a network resource or even a cloud hosting. These attacks can be conducted by anyone, including a hacker or even hostile foreign power. For instance, if in case your primary cloud suffers an attack, your workloads can be immediately shifted to other cloud environments.

Insight All types of cloud are developing, be it public, private or hybrid; therefore huge enterprises can openly embrace multi-cloud service management to meet their divisional operations. Reap many benefits while keeping challenges and risks to a minimum level by adopting a multi-cloud strategy. We are confident that multi-cloud is here to stay and enterprises should adopt it without giving a second thought. Get in touch with our consultant and learn how you can get started.

On-premises to AWS cloud migration: Step-by-step guide

Businesses are rapidly migrating corporate data to the cloud. Based on a report by Thales’ finding, it has doubled in cloud storage usage from 30% in 2015 to 60% in 2022. The figure is steadily increasing as businesses recognize the myriad benefits it has to offer. Moving your data to clouds can help you with:

Increased agility and scalability

Improved performance and reliability

Easy implementation of technologies

Reduced costs

Despite knowing the numerous benefits of cloud migration, concerns about security and hidden maintenance cost prevent businesses from fully embracing it. The optimal solution for addressing these concerns is consolidating all your cloud requirements under one roof, leveraging platforms such as AWS.

Businesses looking forward to migrating existing infrastructure software/ business applications from on-premises to AWS cloud require involvement from stakeholders across all levels of an organization. Therefore, this process requires careful planning and a step-by-step process for successful implementation.

Each migration is unique as business goals of every organization are different. Hence, before aiming for a successful migration to cloud, take time to consider the goals intended to achieve through it. Identify key business drivers and align them with your migration strategy to achieve set goals.

Step1: Migration preparation

The primary objective of the AWS Cloud Adoption Framework is to bring stakeholders together and formulate an action plan that facilitates the transition of the team from cloud goals to actual cloud implementation. In the preparation phase, the following things will be determined, to formulate the right migration strategy from on premises to cloud.

(i) To ensure project success, identify the key stakeholders involved. It includes the teams participating and a designated project manager to lead.

(ii) Connect with each department and have an open discussion about their app usage, pain points, and desired functionalities.

(iii) To ensure compliance and mitigate risk, clearly state the detailed regulatory requirements and security considerations associated with workload, along with any other relevant requirements.

(iv) Perform dependency mapping to gain better visibility into interdependencies of business services and apps.

Step 2: Planning and strategizing

Pinpointing the first domino in a complex migration is the true test. When data is scattered across silos, choosing the right starting point can be difficult. Having the right data and the right expertise by your side can help you get through this.

Once you have all the prerequisites with you, the 1st step is to determine which applications to include in the 1st phase of AWS cloud migration strategy. The best approach is to start with applications with lowest number of dependencies. Another approach could be to start with the workloads that have the most overprovisioned, or idle resources.

Industry research suggests that as many as 30% of on-premises servers, both physical and virtual, are Zombies- showing no sign of useful compute activity for 6 months or . If a business rightsizes their cloud deployment on AWS, these workloads will see a great difference in price or performance, once migrated.

The next step is to decide on the migration strategy, which can be anyone of the following options:

a. Lift and shift: Quickly move your application to AWS with minimal changes, utilizing migration tools for assistance.

b. Partial refactor: Retain certain aspects of your application while rebuilding other parts for proper functioning on AWS. Alternatively, build additional supporting services alongside the existing application.

c. Full refactor: Completely rebuild your application for optimal use of AWS Cloud benefits, considering opportunities like transitioning to microservices or adopting a container-based architecture.

d. SaaS or PaaS transition: Integrate SaaS or PaaS solutions for commodity applications or components, such as email or CRM, to accelerate migration and reduce management overhead.

Deciding on the right team to architect, build, migrate, and manage your cloud can be overwhelming. Hence, many companies opt for AWS migration services to go through the first phases of migration alongside their team.

Step 3: Design

This phase of migration is strategic as it determines the architecture of the AWS cloud infrastructure. While designing the infrastructure, business needs are analyzed, and the best-suited instance type is recommended to maximize cloud investment.

The objective is to deliver a targeted plan approved by all stakeholders as outlined in the initial step. The process usually involves below steps:

a. Examine the performance data across CPU, memory, network, and disk for servers, and across throughput, capacity, and IO for storage.

b. Decide the desired “headroom” (usually 25%) for each asset and assess actual minimum, maximum, and average usage across metrics. Identify the most suitable AWS instance type based on the analysis.

A virtual machine is considered undersized if its CPU demand exceeds 70% for more than 1% of any given hour and oversized if it stays below 30% for more than 1% of a 7-day period.

c. Develop an AWS design, including an architecture diagram and a service list (Amazon EC2 instances, EBS volumes, VPCs, etc.), along with associated costs.

d. Early engagement with security and compliance teams is crucial. Proactive collaboration helps prevent delays and ensures project deadlines are met.

Step 4: Migration and validation

It’s execution stage. Meticulously follow the approved AWS architecture plan and carefully migrate your application and data to the chosen configuration.

Let cloud engineers build approved architecture using AWS CloudFormation.

Further configure each application using Amazon Machine Image (AMI).

Store AWS CloudFormation template and Puppet/Chef scripts in a versioned code repository (Git).

Migrate servers, databases, and data to AWS through internet transfer or AWS migration services for faster transitions.

Conduct initial testing with cloud engineers by repeatedly tearing down/rebuilding infrastructure with AWS CloudFormation.

Other teams test and validate application performance, security, compliance, etc.

Important: When moving data and applications to AWS Cloud, both your old system and the new AWS one will be running at the same time. This can lead to higher cost for that period. Hence, make sure, this additional cost is taken into consideration while formulating AWS Cloud migration strategy. Learn more about the impact of automation on cloud migration.

Step 5: Operate and optimize

The secret to long term success with AWS platform is to keep optimizing. Once migration is completed, there is ample time to address any issues that may not have surfaced during the testing phase. This allows for ongoing improvements to the infrastructure, making it progressively better.

24*7 Support

Before going live, clearly lay down the roles and responsibilities, and list the procedures for common tasks such as instance rebooting, access management, etc. Relying on external AWS migration service providers like Softweb Solutions can help with reducing this additional burden of management.

Cost tracking and analysis

Leverage AWS for real-time billing updates and spending alerts. Optimize cost management by using a comprehensive analysis and governance platform. Your dashboard should offer a unified view of both on-premises and cloud environments, easily accessible by your cloud engineering team for budget oversight. Schedule regular reviews with your team or Managed Services Provider to stay updated on environment costs, especially with AWS introducing new products and services that may impact expenses.

Partnering with an AWS service provider brings expert guidance, streamlined processes, and ongoing support. They’ll navigate the complexities, choose the optimal path, and ensure a smooth, fast, and cost-effective journey to the cloud.

Approach cloud migration strategically

Based on the “Guidebook Understanding the Value of Migrating from On-premises to AWS for Application Security and Performance, Nucleus Research, June 2020” migrating to AWS delivers:

Working with a cloud provider like AWS allows you to access and benefit from powerful hardware, software and services. AWS, or Amazon Web Services, stands as the most extensive and widely embraced cloud platform worldwide, presenting a range of over 200 fully featured services across global data centers. This ensures high availability as well as fast and efficient storage.

Innovation: Embrace the latest cloud technologies and unlock new possibilities, like using a cloud-powered telescope to scan for future business opportunities.

With these riches within reach, who wouldn’t want to join the cloud migration craze? However, navigating the landscape of the seven Rs without understanding their strengths and limitations can lead to detours and missed opportunities. In the next section, we’ll delve deeper into each R, unpacking their individual characteristics and equipping you to chart the optimal course towards your cloud kingdom.

The seven R’s of cloud migration

The seven R’s represent distinct migration strategies with varying degrees of complexity, speed, and long-term impact on your application portfolio. Let’s explore each R in detail, highlighting its purpose, suitability, and potential limitations:

Source: AWS

1. Rehost (Lift and Shift): This rapid and cost-effective option involves directly migrating applications to the AWS cloud infrastructure without significant architectural changes. Think of it as simply relocating your servers to a cloud data center, leveraging its scalability and resilience. However, this approach may limit long-term agility and cloud-native optimization potential.

2. Relocate: If you seek specific AWS features or multi-cloud flexibility, relocating applications to a different cloud platform might be ideal. This approach requires careful planning and compatibility testing but opens doors to specialized services or cost optimization opportunities.

3. Replatform: When existing architecture impedes cloud optimization, replatforming applications allows you to fully utilize cloud-native principles. This approach involves significant reworking to unlock advanced scalability, elasticity, and resilience. However, it demands substantial resources, expertise, and planning.

4. Refactor: For applications where future-proof agility is crucial, refactoring involves building them completely from scratch, embracing serverless technologies and microservices architecture. This most comprehensive approach unlocks future potential but requires intensive resources and planning.

5. Repurchase: Instead of extensive replatforming, you can repurchase outdated applications for cost-effective cloud-native equivalents offering similar functionality. This approach streamlines maintenance, provides modern features, and leverages the inherent advantages of cloud architecture.

6. Retire: This AWS cloud migration strategy targets outdated, underutilized, or incompatible applications. Retiring these applications liberates resources and simplifies your IT infrastructure, while reducing maintenance costs and potential security vulnerabilities.

7. Retain: For stable and compliant applications, retaining them on-premises ensures operational continuity and minimizes disruption. This approach avoids unnecessary migration efforts and allows you to focus cloud resources on strategic priorities.

By understanding the strengths and limitations of each R, you can confidently choose the most appropriate migration strategy for each application in your portfolio. Remember, a hybrid approach is often optimal, tailoring specific R’s to different applications for successful cloud adoption.

6. Unwavering security and compliance: Prioritize data security and safeguard your reputation. AWS prioritizes multi-layered security controls and adheres to the highest compliance standards. Sensitive data is protected with rigorous measures, building trust with customers and minimizing risk.

Conquering cloud migration challenges

With the seven Rs as your compass, it’s time to chart your course through the inevitable challenges that arise on any AWS migration journey. By anticipating these roadblocks and proactively addressing them, you can ensure a smoother and more successful transition to the cloud. Here are some key obstacles to keep in mind:

1. Complexity and skill gap: Navigating the vast and ever-evolving AWS ecosystem can be daunting, especially for organizations with limited cloud experience. This complexity, coupled with a potential skill gap in your team, can lead to inefficient resource utilization, suboptimal architecture choices, and delayed timelines.

Strategize: Address this challenge by investing in training and certifications for your IT staff, partnering with experienced AWS consultants, and leveraging readily available online resources and documentation. Prioritize understanding core AWS services and best practices to make informed decisions throughout your migration.

2. Security considerations: Migrating sensitive data and applications to the cloud requires meticulous attention to security protocols and compliance regulations. Failure to secure your assets can lead to data breaches, reputational damage, and hefty fines.

Fortify: Implement robust access controls, data encryption, and threat detection mechanisms. Choose security-focused AWS services and adhere to industry best practices. Partnering with AWS security experts can significantly mitigate risks and ensure compliance.

3. Vendor lock-in: While leveraging the full range of AWS services can offer significant benefits, over-reliance on proprietary solutions can create an unhealthy dependence on a single vendor. This can limit your future flexibility and potentially increase costs.

Diversify: Maintain a balance between utilizing valuable AWS services and keeping some workloads on-premises or considering multi-cloud strategies. This approach enhances flexibility and bargaining power in the long run.

4. Cost management: While AWS offers flexible pricing models and optimization tools, managing cloud costs effectively requires ongoing monitoring and proactive adjustments. Uncontrolled spending can quickly eat into your budget and undermine the cost-effectiveness of your migration.

Optimize: Implement strategies like reserved instances, cost tagging, and resource auto-scaling to control expenses. Regularly review your cloud bills and identify areas for optimization. Remember, continuous cost management is the key to maximizing the financial benefits of the cloud.
