Attempt to create animated representation of AWS DevOps pipeline

Though the title says something technical this is just a self-promotion and cheap boasting

Continuing with the boosting as I have been doing this for the past couple of days. No, I am not insane, but wanted to do this by hand and use some shell commands. Initially the scenes were identified as 10 and folders created with a base flowchart made using Libre Office Draw copied into each of the folders.

Finally the full image sequence was copied into “full” with renaming in sequence with the following command.

Before that, the same command was previewed using echo instead of cp as seen below.

And finally all images were in the “full” folder as below.

It was time to invoke ffmpeg as shown below.

ffmpeg -i dop%04d.png -c:v libx264 -an -r 30 ../dop-anim.mp4 -hide_banner

What could have been achieved with paid tools like Canva or many others, with some effort and free tools available with Ubuntu Linux achieved with minimal expense, without considering my work time earnings that should be a concern.

When I went to SJCCD 2024

This is not a technical document but rather a place to show off some pictures which I took. A few of them were posted on Twitter ( now the platform is X) while the event was running. Pictures that I am there have been salvaged from other sources and I wholeheartedly thank those who took those. I don’t want to hurt the feelings of anyone or to poach these. If I knew the person directly I would have asked the permission. Still, if any copyright owners want to take these off, please DM me on LinkedIn as those photos were taken from a LinkedIn post.

The event at St. Joseph’s Group of Institutions, Chennai was stupendous and a grand function. Take this opportunity to thank the staff and management as well as congratulate all those who took the extra effort to make it such a great one.

About 15 new security controls added to AWS Security Hub

AWS Security Hub announced the addition of 15 new security controls through their post yesterday. This should increase the number of controls available to 307. AWS services such as Amazon FSx and AWS Private Certificate Authority (AWS Private CA) are some of the newly added controls that were in demand also. More and enhanced controls of previously supported services like Amazon Elastic Compute Cloud (Amazon EC2), Amazon Elastic Kubernetes Service (Amazon EKS), and Amazon Simple Storage Service (Amazon S3) are also added with this release. For the full list of recently released controls and the AWS Regions in which they are available, suggested to review the Security Hub user guide from time to time.

To use the new controls, turn on the standard they belong to. Security Hub will then start evaluating your security posture and monitoring your resources for the relevant security controls. You can use central configuration to do so across all your organization accounts and linked Regions with a single action. If you are already using the relevant standards and have Security Hub configured to automatically enable new controls, these new controls will run without taking any additional action.

The original announcement on their site is here.

Reference Architecture

Reference architecture for a generic interface for Cloud Search on AWS with a broker in any lambda-supported runtime. For the particular implementation, I chose and used Node.js. Hence any client request is authorized from an API key and hits the aws api gateway which in turn invokes the lambda function. In this function internally the code will do necessary normalization and pass it on to aws Cloud Search and if any response the same is reformatted for adapting as aws api gateway response. Along with this functionality, the lambda broker will write a human-readable version of the request as analyzed from the request with request method as verb keywords and sort direction with a prefix of JSON property names, etc into AWS cloud watch with simple console.log methods. Tried to make it as generic as possible.

An event bridge scheduler will trigger another lambda which will analyze these human readable messages and try to detect any missing indexes which will be auto-created into the Cloud Search and updated into a config file on aws S3. Lots of production testing and fine tuning is pending along with necessary documentation as well as the AWS sam template to deploy the same. As of now, this is just a blueprint and the components are lying in different locations and need orchestration there are no plans to open this on any public repository. But anyone who wants to adopt the design is free to pick this and do it on his own without any commitment to me. By creating this with the self-learning capabilities this system can be used literally by many applications even those that already depend on some kind of custom clumsy backend.

A few real-time use cases could be community member databases, hospital patient records, pet shops and many more. Generally, the request methods should work like POST create a new record, PUT updates a record, DELETE deletes ( or trash ) a referenced record, and GET fetch according with proper documentation the feature can be defined as the client software is designed and developed.

The reference architecture drawing is attached here and that is just my thoughts. Please share if you think this is good enough.

Cloud Migration – A Thought Process

Everybody is running after this and gets stuck at one stage or the other unless their product or application is still in black and white on some notebooks or just in the wireframe and has to be built from the ground up. Now if you are going to build a new application, it can be designed to take full advantage of the cloud by combining multiple microservices, leaving out more time and resources to do the application into a perfectly usable solution. Whereas we are considering migration of existing applications into the cloud. The development language, database as well as design approach of the whole application should be considered when thinking about migration. It means that migration to the cloud should be considered on a case-to-case basis and there is no storyboard which fits all use cases.

Architecture in a Serverless Mindset

Consider designing a simple serverless system to process orders within an e-commerce workflow. This is an architecture for a REST micro-service that is simple to implement.

Simple Rest Architecture

How an order will be processed by this e-commerce workflow is as follows.

  1. Amazon API Gateway handles requests and responses to those API calls.
  2. Lambda contains the business logic to process the calls.
  3. Amazon DynamoDB provides persistent JSON document storage.

Though this is simple to implement, this can cause bottlenecks and failures resulting in frustrated clients at the web front end. Analyze the flow and see the possible failure points. Amazon API Gateway integrates with AWS Lambda with a synchronous invocation method and expects AWS Lambda to respond within 30 seconds. As long as this happens, all is well and good. But what if a promo gets shared over social media and very large users pile up with orders, Scaling is built into the AWS Services, but can reach the throttling limits.

The configuration of Amazon DynamoDB, where capacity specifications do play a lot. AWS Lambda throttling as well as concurrency can also create failures. Large dynamic library linking which requires initializing time also affects the cold start time and eventually the latency of AWS Lambda which could get lost with the http request timeout of Amazon API Gateway. Getting deep into the system, the business logic could have some complications and in case one request cannot be processed due to the custom code written in AWS Lambda could fail without any trace of the request saved into any persistent storage. Considering all these factors as well as suggestions by veterans in this walk of life this architecture could be further expanded to something like the below.

Revised Order Processing Architecture

What is the revision and what do the additional components provide as advantage? Let’s discuss it now.

  • Order information comes in through an API call over HTTP into Amazon API Gateway
  • AWS Lambda validates and populates the request into Amazon Simple Queue Service (SQS)
  • SQS integrates with AWS Lambda asynchronously and automatic retries for failed requests as well as Dead Letter Queues (left out in illustration) could help out
  • Business logic Processed requests could be stored to DynamoDB
  • DynamoDB Streams could trigger another AWS Lambda to intimate through SNS about the order to Customer Support

Digging more into the illustrations and explanations there are more to be done to make this a full production-ready blueprint let’s leave those thoughts to upcoming Serverless enthusiasts.

Conclusion

I strongly believe that I have been loyal to the core thoughts of being in a Serverless Mindset. Further thoughts of cost optimizing and scaling can be considered with savings plans, AWS Lambda Concurrent provisioning, Amazon DynamoDB on-demand capacity setting and making sure to optimize business logic and reduce latency.

Rearchitecting an Old Solution

It was in 2016 that a friend approached me with a requirement of a solution. They were receiving video files with high resolution into an ftp server which was maintained by the media supplier. They had created an in-house locally hosted solution to show these to the news operators to preview video files and decide where to attach them. They were starting to spread out their news operational desk to multiple cities and wanted to migrate the solution to the cloud, which they did promptly by lift and shift and the whole solution was reconfigured on a large Ec2 instance which had custom scripts to automatically check the FTP location and copy any new media to their local folders. When I was approached, they were experiencing some sluggish streaming from the hosted Ec2 instance as the media files were being accessed from different cities at the same time. Also, the full high-definition videos had to be downloaded for the preview. They wanted to optimize bandwidth utilization and improve the operator’s response times.
