Diving into Istio Service Mesh for Kubernetes

Thu, 01 Apr 2021 00:00:00 +0000

With Containers and Container Orchestration engine like Kubernetes, the deployments of microservice is trivial today. But getting operational insights into that complex network is not.

In this talk, I discussed about the operational challenges with microservice architectures:

Service Discovery
Load Balancing
Failure Recovery
Observability: tracing, metrics, monitoring
A/B Testing, Canary rollouts
Rate Limiting
Access control, end to end authentication
Service to Service encryption

The agenda included:

Surviving the Peak: Optimizing the Cloud to Prevent Downtime

Thu, 10 Dec 2020 00:00:00 +0000

An Egen webinar, recorded ahead of the 2020 peak retail season. I presented alongside Egen co-founder Nandita Potini, moderated by Megan Larson.

The premise was simple enough to state and hard to act on:

System uptime is critical. Whether you’re already in the cloud or considering a hybrid solution, one thing is clear: if your system isn’t ready for peak periods, you will be losing revenue and customers. Optimizing your cloud data and infrastructure will increase system uptime and deliver a seamless customer experience from first touch to the last mile.

Cloud-Native Engineering Principles

Wed, 01 Jul 2020 00:00:00 +0000

A live webinar with Tom Goodwin, Global Head of Futures and Insight at Publicis Groupe, hosted by Egen in the middle of 2020. Tom opened with the line his work is best known for:

Uber, the world’s largest taxi company, owns no vehicles. Facebook, the world’s most popular media owner, creates no content. Alibaba, the most valuable retailer, has no inventory. And Airbnb, the world’s largest accommodation provider, owns no real estate. Something interesting is happening.

12 Factor App Principles for front-end apps

Tue, 11 Feb 2020 00:00:00 +0000

How can we apply 12Factor App Principles to the front-end apps built using Angular, React, or Vue? How do we follow the principle of “Build Once, Deploy Many”? What about environment-based config? Can we answer some of these questions using Docker?

In this talk, I discussed how to apply 12Factor App Principles to the front-end apps while running them in Docker containers. I demonstrated how to use environment based config and implement health-checks for the front-end apps correctly. I used a React based app for the demo, but these principles can be applied to any JavaScript-based front-end framework.

AWS Serverless beyond Lambda - Panel Discussion

Wed, 18 Dec 2019 00:00:00 +0000

What comes to your mind when you hear the word: Serverless? FaaS, AWS Lambda, the Node.js framework, or something else? Or do you think it’s a set of services that don’t require servers?

AWS defines Serverless as “the native architecture of the cloud that enables you to shift more of your operational responsibilities to AWS, increasing your agility and innovation. Serverless allows you to build and run applications and services without thinking about servers”. So, definitely not “lack of servers”. And there is more to it that just the Lambda or FaaS (Function as a Service).

Cloud-Native Engineering Principles

Tue, 12 Nov 2019 00:00:00 +0000

In this meetup hosted by Northeastern University, Boston, I talked about Cloud-Native Engineering Principles that we have been using at EGEN in developing modern cloud-native data and app platforms for our customers in Industrial IoT, Retail, and Healthcare.

The talk was directed at the graduate students of Computer Science (MSCS) and Information System (MIS) courses.

Developing Powerful CLIs using Go

Wed, 28 Aug 2019 00:00:00 +0000

In this meetup, I talked about how to develop powerful CLIs with Go. Custom CLIs are important tools in any automation. I went through a few use-cases where developing custom CLIs makes sense.

Go is the “goto” programming language for the DevOps. We will understand how to start with Go development, local IDE setup, and explore popular packages written in go.

I demonstrated all of it by creating a custom CLI using Go and utilized it to automate a few CI/CD tasks.

Infrastructure as Code with AWS CloudFormation

Tue, 06 Aug 2019 00:00:00 +0000

In this meetup, I went through the process of automating AWS infrastructure and follow Infrastructure as Code (IaC) principles using AWS CloudFormation.

I went through the best practices of writing AWS CloudFormation templates, IDE support available for CF schema validation, and tools to use to test it during the build time.

I also explored when it makes sense to use AWS CloudFormation over Terraform.

This meetup was organized by Cloud Collective meetup group and event details are available here.

Securing Kubernetes API Server with RBAC and AWS IAM
