Serverless computing, especially AWS Lambda, is a darling of Enterprise IT professionals. First entering the spotlight four years ago, Lambda allows the running of code without provisioning or managing servers. Thus it owes its rising popularity to ease of use, scalability and low costs tied solely to consumed compute time. In response to this increased demand for information on serverless computing, Karsun Solutions Data Analyst Sidharth Ramesh recently presented an Introduction to AWS Lambda at the Northern Virginia Linux Users Group. This Lambda 101 style talk served as an introduction to serverless.
Lambda 101
In his talk, Sidharth explains AWS Lambda is a function-as-a-service event-driven model. Sidharth uses the analogy of pushing code, rather than spinning up new instances. He outlines this departure from previous architectures and suggests use cases where Lambda may replace EC2 instances.
He provides an overview of implementation, including strategies for structuring event triggers. Drawing upon his past interactions with the Karsun Innovation Center, he shared lessons learned as well as suggested use cases. These include using Lambda in ETL or scenarios requiring an infrastructure as code approach.

Karsun Solutions offers a portfolio of enterprise modernization solutions to federal and commercial clients. Key among these is Karsun’s cloud migration solution, Cloud Runway. Cloud Runway enables cloud first organizations to migrate legacy systems to the cloud. Karsun recently paired its Innovation Center team with one of their federal customers for a large migration effort using Amazon Web Services (AWS).
The Challenge
The customer approached Karsun to move an app to the cloud in order to reduce costs. Critically, the customer also wanted to limit the impact on business lines during the migration. In any of Karsun’s Cloud Solutions offerings, the goal is to leverage the flexibility and agility offered by the cloud to reduce costs. The approach balances private, public, and hybrid cloud options based on economics, functionality, and security. Migration teams use strategic partnerships, like those with AWS, to build cost-effective high-quality solutions.
Beginning the Transformation Process
Karsun’s Cloud Runaway leverages change management best practices. Migration teams discourage customers from building their own platforms in favor of focusing on the assets and processes already available to them. They start by identifying the processes and tools already in use. First, the team implements Karsun’s GoLean methodology. Teams identify daily process performance and health measures prior to migration. These measures are assessed and tracked throughout the migration to observe and mitigate the impact on development teams.
Once teams are actively measuring their performance metrics, tools are paired with similar cloud-native apps. The objective is to support and nurture the processes already in place. Karsun’s partnership with AWS supports the migration team’s efforts to use their own experience to select the most appropriate tools available. Cloud Runway takes a collaborative to this transition. The Karsun Innovation Center pairs one of its teams with the migration team. In bringing this in-house research and development team on board, the migration effort utilizes the latest enterprise architecture solutions.
Combining Karsun’s change management approach with strategic cloud partnerships, the customer was able to quickly migrate to the cloud with limited interruptions to their business lines.
