▬▬▬▬▬▬ Description of the video ▬▬▬▬▬▬
As cloud architects, designing and implementing a highly available and fault-tolerant infrastructure for our applications is critical. One way to achieve these goals is by leveraging Azure Spring Apps, a platform as a service (PaaS) offering that allows developers to easily deploy and manage Spring Boot applications in the Azure cloud.
One of the key features of Azure Spring Apps is the ability to deploy applications in a zone-redundant configuration, which ensures high availability and fault tolerance. In this configuration, the application is deployed across multiple availability zones within a region, providing redundancy in case of a zone outage.
The main component of this infrastructure is the Azure Spring Cloud Instance, which is a fully managed service offered by Azure that runs Spring Boot applications. This instance provides features such as scaling, load balancing, and fault tolerance to ensure the availability of your application. To securely connect this instance to other resources, we make use of Virtual Networks (VNet), which is a logically isolated network in Azure that allows you to connect Azure resources to each other, on-premises networks, and to the internet.
For managing web traffic to your application, we use the Azure Application Gateway, which is a web traffic load balancer that provides advanced traffic management capabilities such as SSL offload, cookie-based session affinity, and URL-based routing. The App Gateway is used to distribute traffic across the Azure Spring Cloud Instance deployed across multiple AZs, making the application highly available.
To store application data, we make use of the Azure SQL Database, which is a fully managed relational database service that provides high availability, security, and performance. This database service is used to store the application data for the Azure Spring Cloud Instance.
Other Azure resources used in this infrastructure include Resource Group, Subnets, Public IP, DNS Zone, Private DNS Zone, KeyVault, Spring Cloud Service, MySQL Database, MySQL Server, and Private Endpoint. Each of these resources plays an essential role in ensuring the smooth functioning of the infrastructure. For example, Resource Group is used to logically group resources together, Subnets are used to segment and secure the network, and KeyVault is used to securely store and manage cryptographic keys and secrets.
However, implementing this infrastructure comes with its own challenges. One such challenge is ensuring that all the Azure resources are set up correctly and are integrated with each other. Additionally, ensuring the security of the infrastructure is crucial.
By using Terraform commands, Tfsec, Infracost and Drift detection into our CI/CD pipeline, we can ensure that our infrastructure code is high-quality, secure, and cost-effective. We can catch syntax errors, potential issues, and security risks early on, reducing the likelihood of errors and outages in production. We can estimate the cost of our infrastructure changes in real-time, allowing us to optimize our infrastructure for cost-effectiveness. Additionally, using drift detection helps to identify changes that may have been introduced outside of the established processes and allows for quick remediation to maintain the desired state of the infrastructure.
