Shift2EKS: Migrating legacy / monolithic applications on EKS

Monolithic legacy applications place a heavy burden on both technology budgets and daily operations. Their high maintenance costs and inability to adapt to changing business needs make them ineffective. The inherent complexity, fragility, and lack of integration often result in a negative customer experience and hinders overall business growth.
Kubernetes has become the standard for running modern applications at scale. Businesses aiming to modernize often have questions such as:

• Can we migrate our legacy or monolithic applications to Kubernetes?
• What adjustments are needed to run our applications on EKS?
• How can we migrate to AWS EKS smoothly without disrupting operations?

Shift2EKS service is designed to enable businesses to:

• Boost performance, availability, security, and visibility by leveraging a fully managed Kubernetes environment on AWS.
• Achieve faster time to market through the automation and orchestration capabilities of EKS, enabling quicker deployment cycles and reduced development bottlenecks.
• Improve reliability and resilience with applications running on optimized, multi-availability zone infrastructure, reducing downtime and enhancing business continuity.
• Scale seamlessly by utilizing EKS's ability to handle fluctuating workloads, ensuring consistent performance and resource efficiency as demand grows or shrinks.
• Optimize business and IT operating models for greater efficiency, enabling faster innovation and simplifying daily operations. IT staff will spend less time on routine management tasks, allowing them to focus on driving business value and innovation.

The Solution: From our experience, the quickest path to modernizing applications is to first migrate to Kubernetes using a lift-and-shift approach with minimal modifications. This method involves moving workloads from on-premises to AWS with little alteration. Once the application is up and running on Kubernetes, modernization can start. Certified Skaylink engineers will take charge of the migration process and will move your data and applications from an on-premises location to AWS EKS. Quickly reduce your on-premise infrastructure cost, minimize your dependencies on datacenters and quickly improve gaps in security or legacy tech through lift-and-shift migration to AWS. Keep your applications running with minimal changes and disruption by implementing a lift-and-shift migration strategy. No upfront code refactoring, no need to re-architect your applications — just a quick and painless migration to AWS.

Process of Migration:

• Assessment (up to 1 month): Our engineers will provide you with an in-depth assessment of current application workloads, integrations, data and in and out connections. Using the lift-and-shift methodology we’ll select the right tools and practices, offering you a concrete migration plan that includes our methodologies, estimated costs, and a delivery timeline. The main goals are to understand the current state, identify potential challenges, and outline the benefits of moving to AWS EKS.
• Setting Up EKS Cluster PoC (up to 1 month): After deploying the target infrastructure at a smaller scale, Skaylink DevOps engineers will build a PoC (proof of concept) with the actual application as a staging/development environment. Collaborating with your developer teams our engineers will overview the EKS capabilities in order to provide operational readiness.
• Migrating (up to 6 month): Skaylink DevOps engineers will finalize the infrastructure and migrate everything, taking client downtime requirements into account during cutover. When everything is ready, traffic is shifted to AWS.
• Optimization and Maintenance: After migration, Skaylink DevOps engineers establish detailed monitoring for Kubernetes, providing visibility into infrastructure and application metrics. Our AWS-certified engineers take care of your day-to-day Cloud operations — introducing architectural efficiencies and maximizing your ROI.
