Recently, due to certain tasks, it has begun to automate the operation and maintenance of the cloud computing environment, and the goal is to provide enterprise users.
First consider the mistakes you can't make and take a shot.
Common mistakes when migrating to the cloud
1. Architectural changes
During software development, there is a high dependence on physical hardware and technology stacks. It is usually called a "tightly coupled" architecture. Cloud computing resources and separates many physical environments, that is, a "loosely coupled" architecture. The software is "unacceptable".
Although the cloud can be scaled vertically, it is more horizontally scaled, that is, adding new devices on the existing basis and letting them run together.
2. Unrealistic expectations
Many existing successful cases have inspired too many people, just like the famous "twists and turns" curve, the enthusiasm has faded, and the disappointment is very great.
Don’t try explosive growth. Instagram’s 100,000 users in three months is just an example.
3. Poor understanding of cloud security
Security cannot be accomplished by hardware alone, but must be planned and designed in software.
4. Suitable business options
The development teams of many companies have technical preferences, and these preferences will affect judgment, especially the choice of platform. They tend to prefer the favorite rather than the appropriate one.
5. Preparation for service stop
Since it is the cloud, there is no guarantee that the environment is truly highly available, and there will still be downtime. For example, Amazon has appeared several times.
6. Respond to changes
Just like agile development methods, actively face the changes brought about by changes.
7. Technical debt
Many companies do not have the technology to achieve, but it is not advisable to force the heat.
8. Customer needs
Need to actively guide customer needs to achieve a win-win situation
9. Higher cost
Many people think that cloud computing is reducing costs, but compared with the past, less is the purchase cost of infrastructure, but the cost of operation and maintenance, recovery and disaster tolerance is more. Various cloud service models also bring a lot of additional costs.
