Azure Resource Manager (ARM) templates and Azure Bicep are both used for infrastructure as code, but they have differences. ARM templates are JSON files, whereas Bicep is a more concise, human-readable language that translates to ARM templates. Bicep is preferred when code maintainability is a concern, as it reduces the complexity of ARM templates. However, ARM templates provide more granular control, which might be necessary in complex scenarios. It’s advisable to use Bicep for most cases, but you might choose ARM templates for specific requirements or when working in a mixed environment.
Azure Service Fabric is a distributed systems platform that simplifies the development and management of microservices-based applications. It uses a combination of stateless and stateful services, actors, and reliable collections to manage application components. Stateful services are crucial for maintaining data consistency, while stateless services are for computational work. Actors provide a framework for managing stateful objects. Service Fabric provides automatic scaling, rolling upgrades, and failover, making it suitable for complex microservices scenarios. Understanding these concepts is key to designing scalable, resilient microservices on Azure.
Azure Confidential Computing is a security feature that uses hardware-based Trusted Execution Environments (TEEs) to protect data during runtime. TEEs ensure that data remains encrypted even when processed by the CPU. This technology addresses security and privacy concerns by safeguarding sensitive data from even privileged access. It’s ideal for scenarios where data privacy is paramount, such as healthcare and finance. Understanding how Azure Confidential Computing works and when to use it is vital for securing sensitive workloads.
