+# Lab 10 - Submission
+
+## Task 1 - Artifact Registries Research
+
+### Service names by cloud
+
+- AWS: Amazon Elastic Container Registry (ECR) for container/OCI artifacts, plus AWS CodeArtifact for language package registries.
+- GCP: Artifact Registry.
+- Azure: Azure Container Registry (ACR) for container/OCI artifacts, plus Azure Artifacts feeds for package registries.
+
+### Comparison Table - Artifact Registry Services
+
+| Cloud | Service | Supported artifact types | Key features | Integrations | Pricing model (high level) |
+| --- | --- | --- | --- | --- | --- |
+| AWS | Amazon ECR | Docker/OCI container images and artifacts | Managed private registry, image scanning (basic/enhanced), replication, IAM/KMS security controls | ECS, EKS, Lambda container images, CodeBuild/CodePipeline | Pay for storage, data transfer, and selected actions (for example replication/signing features) |
+| AWS | AWS CodeArtifact | Cargo, generic, Maven, npm, NuGet, PyPI, Ruby, Swift | Package feed hosting, upstream repositories, access control via IAM | CI/CD tools (npm, Maven/Gradle, twine, nuget/dotnet), AWS developer toolchain | Pay for storage, requests, and data transfer out |
+| GCP | Artifact Registry | Docker/OCI (+ OCI Helm), Maven, npm, Python, Apt, Yum, Go, generic, others | Single managed service for many artifact formats, vulnerability scanning support, regional or multi-regional repos | GKE, Cloud Run, Cloud Build, Binary Authorization / Artifact Analysis ecosystem | Pay for storage, data transfer, vulnerability scanning (if enabled) |
+| Azure | Azure Container Registry (ACR) | OCI/Docker images and related artifacts | Managed private registry, geo-replication (Premium), zone redundancy (supported regions), enterprise auth/network controls | AKS, Container Apps, App Service containers, Azure Pipelines/GitHub Actions | Tier/SKU-based model with storage and network transfer considerations |
+| Azure | Azure Artifacts | NuGet, npm, Maven, Python, Cargo, Universal Packages | Multi-type feeds, upstream sources, package governance in Azure DevOps | Azure Pipelines, Azure DevOps repos and release workflows | Consumption-based billing with free storage tier and pay-as-you-go overage |
+
+### Analysis
+
+For a multi-cloud strategy, I would use an OCI-first baseline and keep registries close to workloads in each cloud:
+
+- ECR for AWS runtimes,
+- Artifact Registry for GCP runtimes,
+- ACR for Azure runtimes.
+
+This avoids unnecessary cross-cloud egress and gives native IAM/network integration in each platform. If one service had to be selected as a "single default" for broad artifact format coverage, GCP Artifact Registry is strong because it supports many package formats in one product.

+
+## Task 2 - Serverless Computing Platform Research
+
+### Primary serverless services by cloud
+
+- AWS: AWS Lambda.
+- GCP: Cloud Run and Cloud Run functions.
+- Azure: Azure Functions.
+
+### Comparison Table - Serverless Platforms
+
+| Cloud | Primary service(s) | Runtimes / language support | Execution model | Performance notes | Duration limits | Pricing model |
+| --- | --- | --- | --- | --- | --- | --- |
+| AWS | AWS Lambda | Managed runtimes (for example Node.js, Python, Java, .NET, Ruby) + custom/container runtimes | Event-driven functions, HTTP via API Gateway/Lambda URLs, async/event triggers | Fast autoscaling, cold start depends on runtime and package size | Up to 15 minutes per invocation | Pay per request + compute duration (with free tier) |
+| GCP | Cloud Run + Cloud Run functions | Cloud Run functions supports Node.js, Python, Go, Java, Ruby, PHP, .NET; Cloud Run supports any containerized language/runtime | HTTP services, background jobs, event-driven functions | Request-based or instance-based billing; scale-to-zero; good for containers and APIs | Cloud Run functions (2nd gen): up to 60 minutes for HTTP/event functions | Pay-per-use (CPU, memory, requests/data transfer with free tier components) |
+| Azure | Azure Functions | C#/.NET, JavaScript/TypeScript, Python, Java, PowerShell, custom handlers | Event-driven functions + HTTP triggers + bindings to Azure services | Dynamic scale by plan; strong Microsoft ecosystem integration | Consumption plan max 10 min; other plans have larger/unbounded limits with platform caveats; HTTP response limits still apply | Consumption/Flex/Premium/Dedicated variants; consumption billed by executions + resource usage |
+
+### Platform choice for a REST API backend
+
+I would choose **Cloud Run** for a containerized REST API backend because:
+- any language/runtime via containers,
+- simple deployment model,
+- scale-to-zero when idle,
+- clean path from small service to production traffic.
+
+A close alternative is AWS Lambda + API Gateway when event-driven functions and deep AWS integration are top priorities.
+
+### Reflection - Pros and cons of serverless
+
+#### Advantages
+- No server management and lower operational overhead.
+- Built-in autoscaling and fast time-to-deploy.
+- Cost-efficient for bursty/variable workloads.
+
+#### Disadvantages
+- Cold start effects (runtime/workload dependent).
+- Provider-specific integrations can increase lock-in.
+- Hard limits (timeouts, payloads, concurrency/quotas) require architectural care.
