I've been thinking about it lately so I wanted to blog about how Vogon handles requests.

If you have no interest in web frameworks feel free to skip this one.

Vogon as a core framework is basically nothing. It's a few functions, some starter classes, and a codified file structure. The main idea was for it to be hugely flexible without getting in the way of whatever project it was applied to.

This means that it has no static routes. By design there are no specific php URIs built into the code. And I don't mean that in the WordPress way where there are no static routes, except for the login url (and some other items). There are no static routes. If the framework is used as intended, the only PHP file your request is routed to is the main index.php file of the vogon folder structure.

What that means is that when you enter a url for a vogon instance you'll enter in something like this:

localhost/vogon/ebooks/view/53066?file=/upload/ebooks/user/hack2e_03.book/hack2e_03.book - user.pdf

If you know your URL structure we can go ahead and break this request down a little

[protocol] - http:// (implied because no protocol is specified) [hostname] - localhost (this is an alias for the local ip which is usually 127.0.0.1, or you are requesting something running on your own computer) [uri] - /vogon/ebooks/view/53066 [GET Variables] - ?file=/upload/ebooks/user/hack2e_03.book/hack2e_03.book - user.pdf

When vogon is installed, it analyzes the URI of the request that accessed the installer (though this is user overridable), this allows the framework to be aware of when it is in a subdirectory rather than an exclusive url. That is the case with this request, so we can break our URI into two sections:

[Vogon Root URI] - /vogon [Vogon Route] - /ebooks/view/53066

Before we break things down further we should talk about what's happening in the framework itself. The protocol, hostname, and Vogon Root URI tell the web server to send a request to Vogon application. The web server is then configured to route that request to the index.php file inside the web root. The exception for this is direct access to static files. This enables us to load static assets like JavaScript or CSS files. It does also mean that standalone PHP files can be accessed, but Vogon controller model and view files are all dependant on being loaded through their helper functions and will only error, if anything at all, if loaded directly. An optional security file can be prepended to ensure no unauthorized php execution occurs, but that involves some intensive configuration by the user, and sometimes results in false positives.

Getting back on topic. The request is routed to the index.php file. The index then looks for a new install flag file in the main directory. If this file exists then the install process has not been completed and the installer is loaded.

However, if that file does not exist, the system will load the bootstrap.php file from the /main/ directory, which is where 99% of the Vogon code lives.

The bootstrap loads any classes in the /main/class/autoload/ folder, establishes a database connection if one is configured, and loads our functions from the /main/functions.php file. If user sessions are enabled by the user extension, the bootstrap will attempt to establish an existing user session, if it can't a login screen is shown.

This login screen will be shown to any request, this is useful because unlike other systems with a static login route, you post your login to the same uri you requested originally, so no complicated redirects have to be done.

So far we haven't done any route parsing, and everything done by the system is the same for every request. But now we must calculate what other files need to be loaded, so we load /main/router.php

I think I'd actually like to move this to an extension so it's borders are a little better defined and it can be replaced/configured a little more easily (and so the system can include additional routers to choose from).

The media server version of Vogon is the most mature, so let's discuss that router.

In this router, the router only handles the first step of the process, the endpoint. In our example url that would be '/ebooks'. The router takes the endpoint it's been given and compares that against a database `routes` table. The routes table links controllers to endpoints. These controllers can live in the /main/controller/ folder or in a /main/ext/[ext-name]/controller/ folder. The system will attempt to load the defined controller, if no controller is found it will load the default 404 controller (404 is the http status code for "Not Found").

Then the controller is able to take over routing however it would like. This route is currently configured to use the /main/ext/ebooks extension, and loads controller.main.php from within that extension.

Vogon has a built in function called get_slug_part(); that allows parts of the URI to be accessed as if they were an array. The router uses slug[0] to determine the endpoint, so most controllers look first at slug[1] to determine what action to take. Remember, we are looking at this part of the URI /view/53066

The ebooks controller.main.php uses a switch case based on slug[1]. In this case slug[1] (view), tells the controller that we are viewing an ebook. The ebooks extension then loads controller.comic_book_reader.php.

controller.comic_book_reader.php gets slug[2], checks to ensure that it is numeric (and thus presumably a database ID), and then it attempts to look up that document by database ID. It compares the type of that document (if anything successfully comes back) against a subset of types it knows how to handle, and if it can it loads that document into a view and you are served what you requested.

In this particular instance, that view is the JS PDF library developed by Mozilla, that has been configured to read the filename of the PDF to load from the "file" GET variable.

That's it. That's a full request handled by Vogon. This is the point where output is actually returned to the user (if they have a user session).

Here's the full url again: localhost/vogon/ebooks/view/53066?file=/upload/ebooks/user/hack2e_03.book/hack2e_03.book - user.pdf

And here's a flow of documents (this is not complete and does not include classes, inline includes, ect.):

/index.php -> /main/bootstrap.php -> /main/router.php -> /main/ext/ebooks/controller/controller.main.php -> /main/ext/ebooks/controller/controller.comic_book_reader.php -> /main/ext/ebooks/view/view.js_pdf_viewer.php

I would like people's thoughts on a particular matter.

I've made a personal rule, of not posting pictures of a craft or its process of said craft, I've chosen to make as a gift, until the recipient has received it. The issue is, is that by the time schedules and possible shipping times have lined up, I forget to post anything I've remembered to take photos of. Because of this, it adds to the lack of activity on updating my pages. So, to increase activity, I want to post my projects (especially the gifts) without any specifics on who they'll go to, until the individual has opened their gifts.

Should I do this new idea? Or should I continue as I have been?

Apollo Hospitals at Google Cloud microservices zero-downtime

Zero downtime migration of a complex micro services application to Google Cloud for Apollo Hospitals

Achieving zero downtime migration of a complex micro services application to Google Cloud for Apollo Hospitals, a healthcare company based in Chennai, India. One of India’s largest multidisciplinary healthcare systems, it offers online doctor consultations, home diagnostic tests, and online pharmacy to make healthcare affordable and accessible.

This blog describes how it migrated a critical 24×7 national application with 97 services and 40+ SQL databases to Google Cloud with zero downtime.

Growing faster with better performance, security, and reliability

COVID-19 presented new growth challenges for Apollo Hospitals, which was founded before the pandemic. Google needed rapid development in functional and non-functional areas to meet demand. Apollo 24|7 deploys VMs and containers. The application integrates SQL and NoSQL databases, Redis, VMs, Kubernetes, load balancers, WAF, and third-party public endpoints.

After the pandemic, google engineering leadership saw an opportunity to improve platform performance, security, and reliability to continue growth. Modern automation and Infrastructure as Code (IaC) interventions would improve robustness and scale. To provide affordable healthcare to the masses, cost efficiency was prioritized. her app has millions of active users, so needed to avoid downtime to maintain user experience.

They collaborated with award-winning Google Cloud partner Searce to implement to needs smoothly. Apollo Hospitals, Searce, and Google Cloud teams collaborated on development, testing, deployment, and monitoring, which helped the migration project succeed.

Search supported google teams throughout the project with expertise and support.

Full-stack migration without downtime

The goal was to migrate the entire app to Google Cloud without downtime. The QA, pre-production, and production environments were included.

Google process is outlined below:

DORA survey, then CAST assessment.

Developed migration waves, dependency graphs, and vulnerable library fixes

Created a Google Cloud enterprise landing zone and enabled posture management security controls.

Virtual machines, GKE cluster, Cloud SQL, and Redis instances

Built CI/CD pipelines for all services

Deployed Google Cloud services and dependencies

The Google Cloud Marketplace allows ISV services.

Connect source DBs to Cloud SQL for change data capture (CDC).

Split traffic between services to Google Cloud before the final cutover.

CI/CD pipelines, Terraform scripts, and other resources were used to deploy the QA environment on Google Cloud.

Google next environment was a pre-production replica of the production environment with lower capacity due to low traffic. Simulating a production migration helped us write the right SOPs for each application service. Then also defined service dependencies, split traffic between the old locations and Google Cloud, and tested the functionality end-to-end by sending 1-10% of service traffic to Google Cloud. They installed CDC for databases between source and target on Google Cloud and migrated all traffic to Google Cloud to complete the cutover migration.

They used many pre-production lessons during production migration. On migration day, Identity and Access Management (IAM) issues in a few services integrated with third-party services like payments caused some issues. During partial deployment on GKE, service pods communicated with source location DBs via internet and/or VPN tunnel. Therefore, bandwidth monitoring and NAT gateway port allocation had to be closely monitored to avoid packet drops. Traffic splitting allowed us to divert all traffic from Google Cloud if issues arose. This enabled a zero-downtime application migration.

This migration’s main achievements:

Migration of 97 services across three GKE clusters with gateway and ingress controllers

Used 22 Redis instances, Cloud Functions, Pub/Sub, Kafka.

Took static content to Cloud CDN

Cloud Armor WAF/DDoS, Security Command Center Premium

Select Marketplace services like MongoDB and Aiven Managed Kafka

Split production traffic between the old location and Google Cloud for zero downtime.

Migration of 40+ MySQL and PostgreSQL databases to CloudSQL using CDC

Transferred 2+ TB to Google Cloud.

Reduced operational costs and increased agility and security

Apollo 24|7 successfully migrated through applications to Google Cloud, improving GKE and Cloud SQL performance and latency. Moving away from monolithic code improved architectural tenets and reduced costs by using committed use discounts (CUD) pricing and Google Cloud’s per-second billing, on-demand resources, and custom-sized VMs.

They improved agility and performance by using Terraform to deploy services efficiently with fewer errors using Infrastructure as Code (IaC). The deployment found IAM policy gaps, improving security. Google’s security principles guided thorough cleanup with this project.

Path forward

Apollo Hospitals is also expanding its AI-powered solution partnership beyond the Clinical Decision Support System (CDSS) built with Google Cloud Consulting AI teams. They are introducing Med-PaLM 2 generative AI models for Ask Apollo and beyond.

Google and Apollo Hospitals will continue to transform Indian healthcare. Google Cloud has proven valuable in Apollo 24|7’s core applications, and they want to use it in marketing, supply chain, and customer service.
