Zooming in on the Planning Stage
Planning is indeed the most intricate and decisive step during cloud migration and modernization, so it is vital to go into further detail of this crucial stage. Here are the aspects to consider while planning your cloud migration and modernization process-
Designing the Cloud Architecture
Firstly, you need to design your cloud architecture. This is the blueprint that will guide your entire migration process. It involves:
- Data Architecture- Decide how your data will be stored, accessed, and managed in the cloud. This includes choosing between SQL or NoSQL databases, data lakes, or hybrid storage solutions.
- Application Architecture- Determine how your applications will interact with each other and with your data. Will you use microservices, monolithic, or a hybrid architecture?
- Network Architecture- Plan your network topology, considering aspects like load balancing, VPNs, and direct connections to your on-premises network.
Selecting the Cloud Provider and Tools
The next step is to choose your cloud service provider. Each provider has its own set of services, pricing models, and specialties. Here are some popular choices:
- Azure- Azure is known for its integration with Microsoft’s software and strong support for Windows-based applications.
- AWS- AWS offers a broad and deep set of services and has a large community of users.
- Google Cloud- This is known for high-performance computing, data analytics, and machine learning.
Not all workloads are created equal. Some are more complex, some are more urgent, and some are more valuable to your business. Prioritize them based on:
- Complexity- How difficult is it to move the workload?
- Compatibility- Is the workload already cloud-ready, or does it need to be modified?
- Value- How critical is the workload to your business operations?
- Urgency- Are there any time-sensitive factors that make it more urgent to migrate this workload?
- Interdependencies- Does this workload rely on other workloads? If so, they may need to be moved together.
Choosing the Service and Deployment Models
Based on your needs, you’ll have to choose between different service models like IaaS, PaaS, or SaaS, and deployment models like public, private, or hybrid clouds.
- IaaS (Infrastructure as a Service)- This service model offers virtualized computing resources through the internet.
- PaaS (Platform as a Service)- This provides a platform that allows customers to develop, run, and manage applications.
- SaaS (Software as a Service)- SaaS refers to software that is provided over the Internet.
Selecting Migration Partners and Methods
You don’t have to go it alone. Partners like DiscoverCloud can provide valuable expertise and resources. Also, choose your migration method carefully:
- Rehosting- Rehosting, also known as “lift and shift,” involves moving applications without modifications.
- Replatforming- It involves making a few cloud optimizations to realize some of the cloud benefits but not as much as refactoring.
- Refactoring- This Involves re-architecting and often re-coding an application to fully leverage cloud-native features.
Techniques and Tools
Depending on your needs, you might employ various techniques like containerization, microservices, or serverless computing. Tools such as AWS’s Migration Hub or Google’s BigQuery Data Transfer Service can make the process smoother.
Cloud migration can be costly, especially if not well-planned. Make sure to budget carefully while keeping every team member on board. Remember to account for hidden costs like data transfer fees, and always have a contingency budget for unexpected challenges.
