Enterprises often encounter many problems when they migrate their existing systems to cloud servers.For example: data loss, website crashes, database errors, etc. These problems can lead to loss of time and resources, resulting in damage to the company’s interests.As more and more companies move their servers to the cloud, these issues are becoming more and more obvious. How should we reduce the chances of these problems and provide the least interference to the enterprise to smoothly implement cloud migration?
First, what are the benefits of server migration to the cloud?
1. Reduce investment costs;
2.The latest operating system and the latest infrastructure;
3. It is easier to maintain and manage;
4. Higher flexibility and scalability;
5. Longer running time and a good business chain.
Before starting a migration, you first need to evaluate your internal data. See if these applications or data really need to be migrated to the cloud, and it is completely unnecessary to migrate unwanted data to the cloud.Once the enterprise marks the data that needs to be migrated, it can be used to calculate the required cloud resources and related costs. Importantly, this process can also be used to classify and prioritize workloads, which can reduce costs.
Then there is the test, to ensure a trouble-free migration before the full data migration and start of the cloud server exit.
1, functional testing: software and cloud server management function testing, and testing end-to-end applications for performance issues.
2, integration testing: test the integration between the cloud and legacy systems and SaaS, paying special attention to any interruptions in the chain that will reduce or hinder performance.
3, security testing: Recently, because of the increase in ransomware and malware, it is very important to ensure that all systems and applications have strong security.
4, Scalability and performance testing: The most critical advantage of migrating to the cloud is its scalability. It must be ensured that the system can scale as expected. Scalability and performance testing includes creating stress and load tests to ensure that cloud servers can maintain performance levels at maximum capacity.
Be clear when testing, the nature of the cloud environment and the traditional environment are different, running the perfect data on the traditional server, the results running on the cloud computing solution may be completely different.In the migration process, there are many points and reasons that can lead to instability and failure, such as old systems, aging hardware and energy requirements, tolerances.
In the testing process, try to consider the test content in detail, and must not perfuse the test, but carefully prepare and do everything possible.
In short, cloud computing solutions such as cloud servers can provide dynamic, powerful platform support for the company’s best ideas and innovations, but only if the cloud has been carefully tuned to respond to your website, applications and business needs. Whether it is integration with legacy systems or a large elastic expansion.
