Azure Fundamentals(AZ-900)：クラウドの概念について説明する
学習内容
Describe the benefits of using cloud services
Describe the benefits of reliability and predictability in the cloud
Importance of learning about reliability and predictability:
These are the crucial cloud benefits that help developing solutions.
Reliability
- The ability of a system to recover from failures and continue to function.
- One of the pillars of Azure Framework
Decentralization - process of shifting control from one main group to several smaller ones.
resilient - able to withstand or recover quickly from difficult conditions.
Cloud is decentralized, thus naturally supports reliable and resilient infrastructure.
This enables customers to…
- have resources deployed in various locations around the world
- Even if a service stops from error, there will be ones that are still up and running.
- Cloud environments automatically shift to a different region in some cases.
Predictability
Can be focused on
- performance predictability
- cost predictability
Both are heavily influenced by the Azure Well-Architected Framework
Performance Predictability
Focuses on…
- predicting resources needed to deliver a positive experience for consumers’ customers.
Ex:
- autoscaling
- Can deploy additional resources when consumers suddenly need more resources automatically.
- Can sale back when demand drops automatically.
- load balancing
- Help redirect traffics focused on one area to less stressed areas
- high availability
- Explained in the last article:
Cost Predictability
Focuses on…
- predicting or forecasting the cost of cloud spend.
The cloud can…
- track resource use in real time
- monitor if resources are used in the most efficient way
- find patterns and trend that help better plan resource deployments
- uses cloud analytics and information
Estimates of potential cloud spend can be obtained…
- Tools
- Total Cost of Ownership (TCO)
- Pricing Calculator
