This article will explain in detail whether Cloud Virtual Machine needs to be upgraded regularly. The content of the article is of high quality, so Xiaobian shares it with you for reference. I hope you will have a certain understanding of relevant knowledge after reading this article.

Whether the Cloud Virtual Machine needs to be upgraded depends on its own website or application. If the configuration is sufficient during normal and active periods and there is no abnormal situation, it can maintain the status quo without upgrading.

However, as the business continues to grow, there will occasionally be stuck and slowed down. After repeated adjustments and optimizations, no program or server errors were found, so it is likely that the existing configuration parameters cannot meet normal business requirements because the space has been used for a long time. At this time, the upgrade of Cloud Virtual Machine should be carried out.

The general steps for upgrading a Cloud Virtual Machine are as follows:

Prepare data and programs

Data preparation will be an important part of the cloud host pre-migration process. Its tasks include capturing infrastructure configuration details such as network addressing, CPU specifications, memory, storage. Data preparation requires users to create snapshots of volumes and virtual machines or container images and prepare any database for replication.

Perform upgrade migration

Businesses can copy data to cloud computing environments in a variety of ways, such as network transfers and bulk transfers via removable hard drives. Other options include packaged software and services designed to automatically create disaster recovery environments for specific infrastructure, such as VMware.

Configure Cloud Infrastructure

This is a heavy undertaking. Enterprises create the cloud infrastructure and services needed to host migrated applications and data. This may include setting up cloud service virtual machines, storage volumes, networks, databases, Load Balancer, Access Management, etc.

Testing and optimizing the environment

Before committing workloads, new cloud platform environments must be thoroughly tested under various load and stress conditions and optimized to deliver acceptable performance. Tests should also include various fault conditions to determine the efficacy of redundant systems and resources.

Switch to new environment

Finally, there is the switching and migration of enterprise workloads to the new platform. As with any migration event, this migration is best done during off-hours and low demand times, as there may be some downtime. It is often necessary to resize the database to capture data added since the replication process.
