8 Tips for Deploying a Seamless Cloud Migration Strategy
Cloud computing enables organizations to dramatically scale their operations and provide greater access to their networks while maintaining security and cost-efficiency. Migrating to the cloud can be challenging and expensive, but is well worth the effort once you have successfully moved your data storage and IT operations to a cloud network.
Many businesses are choosing to adopt a cloud environment because the flexibility and scalability of the cloud make it a competitive advantage. A major benefit of cloud computing is that it provides redundancy, which allows you to restore your data. Moving to the cloud can also help companies expand their operations while mitigating the risks of IT outages and data loss.
Organizations can choose between various public, private, hybrid, or multi-cloud solutions. Public clouds are multi-tenant environments, meaning that you share computing resources with other users. They are cost-efficient and easy to manage.
Private clouds are single-tenant environments, so they are more secure than public clouds and offer the customer greater control. The drawback is that private clouds require greater management, and their scalability is limited because you have to acquire new infrastructure to expand.
Many organizations opt for hybrid solutions, which combine private and public clouds to maximize security whilst maintaining scalability and efficiency. You can rely on public infrastructure for less sensitive requirements, and transition to a private environment when handling privileged data. Multi-cloud solutions are similar, except they combine services from multiple providers. However, these solutions can be expensive and complex to manage.
The various cloud services on offer can generally be divided into three categories. Software as a service (SaaS) is the most popular option, as it allows you to access pre-engineered software. The provider handles the technical side so you don’t have to. An example is Gmail. Infrastructure as a service (IaaS) involves renting computing resources like servers and storage space from a cloud provider. Platform as a service (PaaS) combines the two so customers can customize their cloud infrastructure without having to build everything from scratch.
There are several issues to consider when attempting to implement cloud migration. Many organizations fail to adequately plan the move and end up facing unpredicted costs and delays. Some pitfalls to look out for are:
It is important to plan your migration in advance. The following practices can help ensure a smooth and efficient transition to the cloud.
1. Understand Which Cloud Solution Fits Your Needs
Before you attempt to move to the cloud, you need to analyze your workload and research the available cloud services and tools that can help you migrate. Evaluate which cloud offerings meet your operational requirements, taking into consideration cost, usability, flexibility, scalability, security, and access.
You should only select a cloud service that lets you track usage and billing data. Another issue to consider is redundancy and data assurance. You should use a cloud solution that allows you to back up your data easily. For example, AWS clouds allow you to back up your data as EBS Snapshots.
Having a clear migration strategy is the most important element of a successful plan. There are several ways to move your applications to the cloud, including rehosting, replatforming, and refactoring.
Rehosting, also known as lift-and-shift, is the simplest and fastest method. The cloud provider hosts your existing software without you having to modify it first. However, rehosting is not the most efficient way to make the most of the cloud.
Replatforming is the next step up.
