What is the best way to migrate your existing systems to the cloud?

We need to carefully assess the following two key deciding factors and redesign if required before we start our cloud transformation. These factors are the most contributors for operational challenges on day 2 support. Latency. Application Compatibility.

There's no one-size-fits-all answer for cloud migration. It depends on your systems! Here are the common approaches: Lift & Shift (rehosting): Move existing systems to the cloud "as-is" for a quick start, but it may not optimize cloud benefits. Replatforming: Move & modernize applications to leverage cloud features for better performance and scalability. Re-architecting: Completely rebuild applications to be cloud-native, unlocking the full potential of cloud services. The best approach considers factors like system complexity, cost, and desired outcomes. Talking to a cloud specialist can help you pick the right strategy for a smooth migration.

Conduct a thorough evaluation of your current systems, identifying dependencies, performance requirements, and data sensitivity. And, choose a suitable cloud provider and architecture that aligns with your needs, considering factors like scalability, security, and cost-effectiveness.

Define your application requirements, including workload types, data storage needs, traffic patterns, and compliance requirements. And, choose a cloud service model (IaaS, PaaS, SaaS) based on your development and management preferences.

After a comprehensive assessment, craft a detailed migration plan. Start by prioritizing workloads depending on their complexity, dependencies, and the business value they deliver. Next, determine the optimal migration approach for each workload: rehosting (lift-and-shift) or refactoring (rearchitecting for cloud-native). A legacy web application might benefit from rehosting to achieve quick wins, while you can refactor a monolithic e-commerce platform into microservices for better scalability. Finally, establish a timeline, budget, and resource allocation for the migration process—factor in the time and effort required for activities like data transfer, testing, and user training.

As you plan your cloud transition, pay close attention to security and compliance. These critical areas require careful assessment and robust implementation. First, evaluate the security features and compliance certifications offered by your chosen cloud provider. Next, implement comprehensive security measures tailored to your environment. Leverage Identity and Access Management (IAM) and encrypt data in transit and at rest with industry-standard ciphers to limit who can access cloud resources. Also, configure firewalls, security groups, and network access controls to restrict traffic and isolate workloads.
