Cloud design pattern using azure
- 1. Learn Cloud Design Patterns using Azure Karthikeyan VK Karthik_3030@yahoo.com @karthik3030 https://blogs.karthikeyanvk.in
- 2. Enter Text Why Cloud Design Patterns? Availability & Resilience are hard in Cloud. Performance and scalability are taken for granted in cloud. Data management not a trivial Problem. https://blogs.karthikeyanvk.in
- 3. Enter Text Why Cloud Design Patterns? It provides Off-the-shelf solution. Automatically handles quality attributes. https://blogs.karthikeyanvk.in
- 4. Enter Text What is Design Patterns ? Design patterns are typical solutions to common problems in software design. Each pattern is like a blueprint that you can customize to solve a particular design problem in your code. https://blogs.karthikeyanvk.in
- 5. Enter Text Principles based Design https://blogs.karthikeyanvk.in
- 6. Enter Text Why Principles ? Not Technology Bound. Helps decision-making process. https://blogs.karthikeyanvk.in
- 7. Enter Text Solid Principles S- Single Responsibility O – Open Close Principle L – Liskov Principle I – Interface segregation D – Dependency Inversion https://blogs.karthikeyanvk.in

- 11. Enter Text Solid Principles I – Interface segregation https://blogs.karthikeyanvk.in
- 12. Enter Text Solid Principles D – Dependency Inversion https://blogs.karthikeyanvk.in
- 13. Enter Text Cloud Design Principles https://blogs.karthikeyanvk.in Design for self healing. Make all things redundant Design to scale out Partition around limits Design for operations- Deployment, Monitoring, Incident response, Auditing
- 14. Enter Text Cloud Design Principles https://blogs.karthikeyanvk.in Design for Evolution. Use the best data store for the Job Build for the business needs. Think YAGNI
- 15. Enter Text CQRS Pattern Command Query Responsibility Segregation. Command – Create/Update/Delete Query – Select or Fetch https://blogs.karthikeyanvk.in
- 17. Enter Text Strangler Pattern Incrementally migrate a legacy system by gradually replacing specific pieces of functionality with new applications and services. https://blogs.karthikeyanvk.in
- 19. Enter Text Pipes and Filters pattern Decompose a task that performs complex processing into a series of separate elements that can be reused. The processing required by an application can easily be broken down into a set of independent steps. Keep your classes DUMB https://blogs.karthikeyanvk.in
- 20. Enter Text Pipes and Filters pattern https://blogs.karthikeyanvk.in
- 21. Enter Text Circuit Breaker Pattern https://blogs.karthikeyanvk.in Handle faults that might take a variable amount of time to recover from, when connecting to a remote service or resource. Three States – Open, Half-Open, Closed State. Use POLLY – nugget package to implement. Straight forward solution.
- 22. Enter Text Circuit Breaker Pattern https://blogs.karthikeyanvk.in
- 23. Enter Text Compensating Transaction Pattern https://blogs.karthikeyanvk.in Undo the work performed by a series of steps, if one or more of the steps fail. A compensating transaction is application specific. Used in places where there is an eventual consistency Solves the No-SQL world problem with different data store in Microservices
- 24. Enter Text Compensating Transaction Pattern https://blogs.karthikeyanvk.in Used in places where there is an eventual consistency Solves the No-SQL world problem with different data store in Microservices
- 25. Enter Text Static Content Hosting https://blogs.karthikeyanvk.in Deploy static content to a cloud-based storage service that can deliver them directly to the client. This can reduce the need for potentially expensive compute instances.
- 26. Enter Text Static Content Hosting https://blogs.karthikeyanvk.in
- 27. Enter Text Static Content Hosting https://blogs.karthikeyanvk.in May not be suitable in application that needs to perform some processing on the static content before delivering it to the client. For example, it might be necessary to add a timestamp to a document
- 28. Enter Text Gate-Keeper Pattern https://blogs.karthikeyanvk.in Protect applications and services by using a dedicated host instance that acts as a broker between clients and the application Validates and sanitizes requests, and passes requests and data between them.
- 30. Enter Text Event Sourcing Pattern https://blogs.karthikeyanvk.in Instead of storing just the current state of the data in a domain, use an append-only store to record the full series of actions taken on that data. The events are persisted in an event store that acts as the system of record (the authoritative data source) about the current state of the data.
- 31. Enter Text Event Sourcing Pattern https://blogs.karthikeyanvk.in
- 32. Enter Text Event Sourcing Pattern https://blogs.karthikeyanvk.in Apache Kafka, Service Bus, Queue/Blob Storage
- 33. Enter Text Sharding Pattern https://blogs.karthikeyanvk.in Divide a data store into a set of horizontal partitions or shards. This can improve scalability when storing and accessing large volumes of data.
- 35. Enter Text Sidecar Pattern https://blogs.karthikeyanvk.in Deploy components of an application into a separate process or container to provide isolation and encapsulation. Applications and services often require related functionality, such as monitoring, logging, configuration, and networking services
- 37. Enter Text Sidecar Pattern https://blogs.karthikeyanvk.in SSL Termination by application gateway. Health monitoring is deployed as service in the host to be used by multiple services.
- 39. Enter Text Why Anti-Patterns ? Application behaves well during all types of testing. But behaves badly in production. The development team is then faced with two questions: • Why didn't this behaviour show up during testing? • How do we fix it? https://blogs.karthikeyanvk.in
- 40. Enter Text What is Anti-Patterns ? Anti-Pattern is a common practice that is likely to cause problems when an application is under pressure. It's very difficult in a test environment to simulate real users. https://blogs.karthikeyanvk.in
- 41. Enter Text Busy Database Anti-Pattern Offloading processing to a database server can cause it to spend a significant proportion of time running code. Remember stored procedures and triggers ! https://blogs.karthikeyanvk.in
- 42. Enter Text No Caching Anti-Pattern Repeatedly fetching the same information from a resource that is expensive to access, in terms of I/O overhead. Also think about stale data Remember the expiring cache. Absolute or Sliding expiration. Monitor your application and queries https://blogs.karthikeyanvk.in
- 43. Enter Text Chatty I/O Anti-Pattern The cumulative effect of a large number of I/O requests can have a significant impact on performance and responsiveness. Packaging the data into larger, fewer requests Problem seen in improper domain division in Microservices. https://blogs.karthikeyanvk.in
- 44. Enter Text Improper Instantiation Anti-Pattern It can hurt performance to continually create new instances of an object that is meant to be created once and then shared. Think about singleton pattern. Always reuse System.Net.Http.HttpClient or any connection related broker classes https://blogs.karthikeyanvk.in

- Use partitioning to work around database, network, and compute limits

- This pattern may not be suitable: When requests to the back-end system cannot be intercepted. For smaller systems where the complexity of wholesale replacement is low. Testing problem.
- Design your class to be dumb
- Design your class to be dumb Complexity. Idempotency. Repeated messages. Think of poison queue
- Exception handling and failing should be properly thought through.. Logging should be made proper and don’t log toomuch This pattern isn't recommended: For handling access to local private resources in an application, such as in-memory data structure. In this environment, using a circuit breaker would add overhead to your system. As a substitute for handling exceptions in the business logic of your applications.
