    What the heck is Digital Transformation anyway ?

    What the heck is Digital Transformation anyway ?

    What the heck is Digital Transformation anyway ?

    Digital Transformation has caught the fancy of large organisations in the last 5 to 6 years. We get to hear about organisations becoming more digital.And what does this becoming Digital means ? We have been in the digital world and have been using banking services and other online services for well over 15 years now and they are mostly digital as a customer. So what has changed? I tried to address this aspect in the podcast. Like DevOps , if you speak to different people , each will have their own perspective on what Digital Transformation is all about. And to be a great extent , it might be true as well. I would like to bring my perspective on what Digital Transformation is all about, by taking a real world example and applying the core elements of Digital Transformation that involves people , process and technology. I also delve into the metrics , goals and outcomes that are required for Digital Transformation and the evolving trends and process in software engineering that can help to make Digital Transformation successful.

    Hope you like it.

    Deployment Strategies for Modern Infrastructure

    Deployment Strategies for Modern Infrastructure

    In this podcast, we are going to discuss the Deployment Strategies that can be adopted for managing modern infrastructure. Customers are digitally savvy these days and downtime is frowned upon. So how can we plan our deployment in such a way so that there is little to no downtime for the end-users? To arrive on a deployment strategy, we need to understand the requirements to start with and then mapping each deployment strategy with pros and cons. I have discussed on the capabilities and requirements for arriving and deciding on deployment strategies, the various deployment strategies like Recreate, Rolling Updates, Blue Green, Canary and A/B Testing. Monitoring and Deployment Automation is another important aspect that needs to be factored. With Modern workloads in the cloud, Immutable Infrastructure as a paradigm is gaining traction. Finally, we end up discussing the best practices for Safer Production Deployment.



    Some of the topics discussed : 

    Capabilities of Deployment

    1.Provision

    2.Configure

    3.Deploy

    4.Scale

    5.Monitor

     Requirements to firm up a Deployment Strategy

    1.Zero Downtime

    2.Real Traffic Testing

    3.Targeted Users

    4.Cost

    5.RollBack 

    6. End User impact 

    7. Complexity of Setup

    Deployment Types:

    1.Re-create

    2.Blue Green

    3.Rolling Updates / Ramped Up

    4.Canary

    5.A/B testing

    Other factors to be considered :

    -Monitoring and Automation of Deployment

    -Immutable Infrastructure As A Paradigm

    -Tips and Best Practices for Safe Deployment

    Demytisfying oAuth And OpenID Connect

    Demytisfying oAuth And OpenID Connect

    Authentication and Authorization as a concept has been there for a long time. oAuth is the most standard way in which authorization is implemented and OpenID Connect is a preferred mechanism for authentication. In this podcast, we will Demystify oAuth and OpenID Connect - why, what and how. We will briefly touch upon the history of authentication, OAuth Grants, Scopes and Claims. We also discuss the different types of tokens like ID Token, Access Token and Refresh Tokens. We also briefly touch upon the differences between Cookie and Token and finally ending with how API validates these token. I hope you find the topics discussed in this episode useful.

    DevSecOps - Security is not an afterthought

    DevSecOps - Security is not an afterthought

    DevSecOps is a relatively new term coined that focus on the collaboration between Application Development, Operations and Security Teams coming together to deliver applications and software in an agile fashion in an iterative, faster and secure way.

    In this podcast, we discuss the reason why DevSecOps have come into focus in the last few years. And for teams to start adopting DevSecOps practices, what are different aspects, perspectives and approaches that need to be considered are also briefly touched upon. Threat Modelling is the starting point to understand the security posture, identifying gaps and prioritize critical aspects that need attention. We also discuss the tools, technology and automation that are required for successfully building DevSecOps practices.

    Cloud Economics and FinOps

    Cloud Economics and FinOps

    As cloud adoption goes mainstream, the cost and financial impact of running services in the cloud is gaining significance. There is a mindshift change required to think of costs from Capital Expenses ( Capex ) to Operational Expenses ( Opex ) . Architecting solutions keeping the cost as an important lever is mandatory . Using tools like Cost Calculator to better predict cost is recommended. Monitoring the infrastructure to ensure the cost escalation is kept in control by means of alerts , dashboard and monitoring and optimization of resources through automation is becoming more pronounced across organization. We finally discuss on the idea of FinOps - Finance , Operations, Engineering and Senior Management coming together to collaborate and ensure each of them understand the roles and responsibilities . We discuss the main pillars of FinOps - Governance, Engineering, Reporting and Optimization. I hope you find this interesting.

    Infrastructure As Code - Taking DevOps CI- CD Automation to the next level

    Infrastructure As Code - Taking DevOps CI- CD Automation to the next level

    DevOps Continuous Integration - Continuous Delivery CI CD have seen successful adoption in many places . This has helped in the automation of code integration, build and deployment . But infrastructure is always missed out in this process. In traditional on premises world, infrastructure once created will not change very often. But with Distributed Computing and Cloud, infrastructure needs to be created real time and teared down as and when required. There is no way to manually create infrastructure across regions without automating the creation of infrastructure. And these scripts have to be version controlled and treated as another piece of code . It should be part of CI- CD process as well. In this epsiode, I'm discussing Infrastructure as Code and why should Developers , not just DevOps engineers should care.
