Understanding microservices – Comparing Application Components
One of the goals of cloud computing is to provide cost-effective solutions that are dynamic and reliable. In Chapter 7, Designing Compute Solutions, we looked at several different components: containers, Kubernetes, Azure Functions, and Logic Apps. One of the key differences between these services and more traditional compute options, such as VMs, is the ability …

Client certificates – Comparing Application Components
You can configure the Azure API gateway so that it requires a certificate when making calls. Whereas subscription keys are generated by you and can be quickly supplied, certificates provide greater security. However, the certificate must be generated by a certificate authority and securely provided to your consumers. But when security and control are of …

Managing APIs with Azure API Gateway – Comparing Application Components
When building cloud solutions and web applications, it is common to use APIs – specific types of apps that only return data in JSON or XML. This data is then used by a consuming application, a desktop application, a mobile application, or even a website. APIs can be used internally or to expose your data …

Using deployment slots – Comparing Application Components
A powerful feature of app services in Azure is deployment slots. When publishing updates to app services, you need to be confident that your latest changes do not break the existing running application. Although you should always test changes in lower environments such as a development or test environment first, a final production deployment can …
