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: https://praveen.salitra.io/workshops/2021-03-terraform-azure/ Thu, 25 Mar 2021 00:00:00 +0000 https://praveen.salitra.io/workshops/2021-03-terraform-azure/ This half-day online workshop focused the concepts of Infrastructure as Code using Terraform. I chose Azure Cloud as the target Cloud Service Provider and covered: Infrastructure as Code (IaC) Landscape Terraform OSS, Cloud, Enterprise Terraform Concepts CLI State Providers Workspaces Basic Commands Plan vs Apply Modules Hands-On Setup an AKS cluster and Azure PostgreSQL service Review a Production Setup During the workshop, the 40+ attendees followed the hands-on exercises on deploying a microservice in a containerized fashion on Azure Kubernetes Service and accessing those endpoints using Ingress Controllers. https://praveen.salitra.io/workshops/2021-03-cloud-networking-101/ Thu, 04 Mar 2021 00:00:00 +0000 https://praveen.salitra.io/workshops/2021-03-cloud-networking-101/ I went through the concepts of: Network Models (OSI and TCP/IP) IP Addresses IPv4 vs IPv6 CIDR and Subnet Masking Private Networks VPC/VNET, Subnets NAT Gateways Sizing Recommendations DNS Load Balancers Layer 4 vs Layer 7 LB vs Proxy Network Security AWS Security Groups AWS NACLs Azure Firewalls https://praveen.salitra.io/talks/2020-12-surviving-the-peak/ Thu, 10 Dec 2020 00:00:00 +0000 https://praveen.salitra.io/talks/2020-12-surviving-the-peak/ https://praveen.salitra.io/articles/running-kubernetes-workload-amazon-spot-instances/ Wed, 30 Sep 2020 00:00:00 +0000 https://praveen.salitra.io/articles/running-kubernetes-workload-amazon-spot-instances/ Amazon defines a Spot Instance as ‘an unused EC2 instance that’s available for less than the On-Demand price.' I call them significantly cheaper instances that AWS snatches away from you when it can get more money for them. For example, when someone requests an On-Demand Instance or a Reserved Instance, and capacity is close to at-limit, AWS will terminate your Spot Instance to free up capacity for them. An upcoming Spot Instance interruption only has a 2-minute advance notice. https://praveen.salitra.io/talks/2020-09-cloud-native-engineering-principles/ Fri, 25 Sep 2020 00:00:00 +0000 https://praveen.salitra.io/talks/2020-09-cloud-native-engineering-principles/ In this webinar hosted by National Institute of Technology, Warangal, India, 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.

Such a strong one, in fact, that here I am typing furiously into the night. Working on that account and seeing the final results took me aback. They managed to bring down annual cloud costs by a cool $2 million – a saving of 60%! No, they didn’t wave a magic wand. We just needed to take a closer look at their cloud architecture. https://praveen.salitra.io/articles/10-ways-reduce-cloud-costs/ Thu, 20 Aug 2020 00:00:00 +0000 https://praveen.salitra.io/articles/10-ways-reduce-cloud-costs/ https://praveen.salitra.io/talks/2020-07-preparing-for-success-post-covid19/ Wed, 01 Jul 2020 00:00:00 +0000 https://praveen.salitra.io/talks/2020-07-preparing-for-success-post-covid19/ https://praveen.salitra.io/workshops/2020-03-containers-kubernetes-orchestration-aks/ Fri, 06 Mar 2020 00:00:00 +0000 https://praveen.salitra.io/workshops/2020-03-containers-kubernetes-orchestration-aks/ This one-day in-person workshop focused on bringing concepts of Containers and Container Orchestration to the front-end and back-end engineers.

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. https://praveen.salitra.io/talks/2019-12-aws-serverless-beyond-lambda-panel/ Wed, 18 Dec 2019 00:00:00 +0000 https://praveen.salitra.io/talks/2019-12-aws-serverless-beyond-lambda-panel/ 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”. https://praveen.salitra.io/talks/2019-11-cloud-native-engineering-principles/ Tue, 12 Nov 2019 00:00:00 +0000 https://praveen.salitra.io/talks/2019-11-cloud-native-engineering-principles/ 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.

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. https://praveen.salitra.io/articles/method-for-performing-virtual-load-test/ Tue, 13 Aug 2019 00:00:00 +0000 https://praveen.salitra.io/articles/method-for-performing-virtual-load-test/ https://praveen.salitra.io/talks/2019-08-infrastructure-as-code-aws-cloudformation/ Tue, 06 Aug 2019 00:00:00 +0000 https://praveen.salitra.io/talks/2019-08-infrastructure-as-code-aws-cloudformation/ 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. https://praveen.salitra.io/talks/2019-07-securing-kubernetes-api-rbac-iam/ Wed, 17 Jul 2019 00:00:00 +0000 https://praveen.salitra.io/talks/2019-07-securing-kubernetes-api-rbac-iam/ In this meetup, I went through an overview of Kubernetes and then demonstrated how to secure Kubernetes cluster installed on AWS infrastructure via kops or EKS.
