software architecture patterns for Serverless systems

Here is an example that illustrates software architecture patterns for serverless systems: Microservices Pattern - With serverless, you can break down functionality into individual microservices that each handle a specific task. For example, you could have separate functions for user authentication, payment processing, image resizing, etc. These microservices can scale independently and communicate via event triggers or API calls. Event-Driven Pattern   - Serverless functions are commonly triggered by events like HTTP requests, database changes, queue messages, etc. You can build an event-driven architecture where different functions process events from various sources. For example, an image upload event could trigger functions for resizing, metadata extraction and storage. Offline Processing Pattern - Serverless functions can process data asynchronously in the background. For example, you could have a function triggered by a database change that handles intensive data analysi...

certification preparation

Here is a suggested learning path with sample questions for preparing for the AWS Certified Solutions Architect certification: 1. Get familiar with AWS core services and features: - What are the main benefits of AWS? Scalability, flexibility, pay-as-you-go pricing.  - What are the core services offered by AWS? Compute (EC2), storage (S3), database (RDS), networking (VPC), etc. - What is auto scaling and how does it help? Automatically launches or terminates EC2 instances based on demand to maintain performance. 2. Understand AWS security best practices:  - How do you securely access AWS services? Using IAM policies and roles to control access. Using MFA for additional protection. - How do you protect data at rest and in transit? Encrypt EBS volumes, S3 objects, and data in transit. Use SSL certificates.  - How does AWS isolate customer accounts? Through VPCs and security groups. 3. Learn about designing highly available and fault tolerant architectures: - How do you achie...
