Study Notes

Scaling on AWS

The presentation focuses on scaling up to 10 million users.
A search for "scaling on aws" returns ~20M results. This is not specific enough to be helpful
Key considerations for scaling include managing users, maintaining performance in various geographic locations, detecting and responding to incidents, maintaining business continuity, and managing security and compliance.
For scaling, development and testing, managing change, tracking costs, optimizing cost, and minimizing environmental impact are also necessary.
AWS Global Infrastructure contains 34 regions and 108 availability zones (AZs).
A private backbone network connects these regions and AZs.
More than 600 points of presence spread globally facilitate content delivery.
AWS regions define data location, offering protection against legal risks (like GDPR) and enable disaster recovery.
Each AZ is a cluster of data centers, with at least three AZs per region.
AZs protect against technical failures.
Points of presence (POPs) host content delivery services (like Amazon CloudFront) and aren't directly usable.
AWS Local Zones extend regions, located in major cities and industrial centers.
AWS Wavelength infrastructure is designed to bring AWS cloud capabilities to stadiums and entertainment venues.
Data centers are strategically placed for low latency, high performance, and availability.
Outposts extends AWS infrastructure into on-premises data centers, enabling local low-latency applications, data processing, and storage.
AWS provides a wide range of 200+ fully featured services encompassing analytics, business applications, blockchain, security, identity, and compliance, database management, development tools, computing options, media services, and more.
Decisions are reversible (two-way doors).
The presented process for scaling involves building, measuring, and learning iteratively.
The presentation advocates for careful assessments of control versus responsibility, heavy lifting, and distinguishing between serverless, managed, or self-hosted solutions when scaling.
The architecture of a single user application contrasts with the architecture required for thousands or millions of users. Different database architectures are necessary in each case, including self-managed, fully managed solutions such as RDS, DynamoDB, Aurora, and Aurora Serverless.
Key considerations for greater than 10,000 users include further workload shifting, utilizing a multi-region architecture, and monitoring data consistency
A 30:70 read/write ratio is typical.
AWS Amplify simplifies development of web and mobile applications by handling authorization, identity, and much more.
Amplify Studio helps manage, configure, and enhance applications.

Considerations for scaling

Fine-tuning existing solutions, exploring multi-regional options, addressing database performance, and developing in-house tooling are key considerations for scaling beyond one million users.
Purpose-built databases (like graph, ledger, geo-tracking, document, or key-value) for particular needs.
Potential database solutions include federation, sharding, purpose-built databases (NoSQL or graph), and multi-region strategies with cross-region replication potentially including multi-master setup.

Specific AWS Services

Amazon S3: Object-based storage, highly durable, good for static content, infinitely scalable, objects up to 5TB in size, supporting encryption.
Amazon CloudFront: Caching content for faster delivery (dynamic and static content, streaming video, optimized for AWS), custom SSL certificates, short TTLs.
Amazon DynamoDB: Managed NoSQL database, with provisioned and on-demand pricing options; offering fast, predictable performance with full distribution and fault tolerance and with streams and triggers, global tables.
Amazon RDS: Provides managed relational databases, with maintenance, security patch management, and software update management capabilities, with MySQL, MariaDB, PostgreSQL, Oracle, SQL Server, and Amazon Aurora engine options.
Amazon Aurora: MySQL or PostgreSQL-compatible; automatic scaling (up to 64TB); up to 15 read replicas; continuous (incremental) backups; six-way replication across three zones.
Amazon EC2: A virtual compute service for workloads
Amazon Route 53: Traffic routing
AWS Lambda: Event-driven compute service supporting numerous languages.
Amazon API Gateway: Manages APIs
Amazon CloudWatch: Collects metrics and logs, monitors alarms, dashboards, auto-scaling, events, analyze trends and metric math, provides compliance, and security capabilities.
Amazon Cognito: Supports user authentication and authorization.

Additional Concepts

Horizontal scaling: Adding more computing resources.
Vertical scaling: Increasing the resources of a single server.
Load balancing such as Application Load Balancer and Network Load Balancer, distributes incoming traffic across multiple instances for high availability.
Auto Scaling: Automatically adjusts resources to respond to demand changes.
Microservices architecture: Dividing an application into small, independent services.

AWS X-Ray

Supports identifying application performance bottlenecks and errors.
Helps pinpoint the problematic services.
Analyzes the impact on users.
Allows for service call graph visualization.

Key takeaways

The presentation highlights the need for automation, redundancy, and scalability across a wide array of AWS services.
It advocates for adopting multiple services and the SOA architectural approach for higher availability and greater throughput.
Key considerations include understanding and planning your scaling needs.
