Day 27/30 Serverless Best Practices: One log write → CloudWatch Logs + Metrics. CloudWatch EMF = 2 for 1 in a single structured entry=no extra code, no extra cost, business context included. Lambda Powertools makes this super easy.📈

Day 26/30 Serverless Best Practices: Don't log errors. Log which customer, which order, which store. Context is everything, "something failed" is useless, "order #4521 failed at checkout" is actionable. 🔍

Day 25/30 Serverless Best Practices: Retry logic as config (Step Functions) or code (Durable Functions). Either way, don't skip it, unhandled failures in distributed systems compound fast. 🔄

Day 24/30 Serverless Best Practices: SQS DLQ ≠ Lambda on-failure destination. One catches processing failures, the other catches invocation failures. You need both, they're not interchangeable. 🛡️

Day 23/30 Serverless Best Practices: Retries will happen. Idempotency is non-negotiable. Without it, a single retry can charge a customer twice or place a duplicate order. 🔁

Day 22/30 Serverless Best Practices: Provisioned Concurrency = zero cold start. Use it for predictable, latency-critical traffic, then automate scaling so you only pay for what you need. ⏱️

Day 21/30 Serverless Best Practices: SnapStart=init at deploy, not invoke. Sub-second cold starts for Java, Python, and .NET. Zero extra cost. One checkbox. Massive impact. 🚀

Day 20/30 Serverless Best Practices: Cold starts hit <1% of production invocations. They matter for user-facing APIs, not background jobs. Optimise where it actually affects your users. 🧊

Day 19/30 Serverless Best Practices: Stop guessing Lambda memory. Power Tuning runs your actual function at every setting and shows the cost/performance curve. Free, open source, no excuses. 📊

Day 18/30 Serverless Best Practices: When did you last upgrade your Lambda runtime? Python 3.10 → 3.14 showed dramatic latency improvements plus security fixes you're missing. 🔄

Day 17/30 Serverless Best Practices: Don't import the whole SDK. Import only what you need. Every extra KB in your package adds to cold start time and it compounds fast. 📦

Day 16/30 Serverless Best Practices: Sequential → parallel. 300ms → 100ms. Use worker threads to processes records concurrently, allocate >1.8GB to unlock multiple vCPUs and maximise it. ⚡

Day 15/30 Serverless Best Practices: Step Functions = service integrations. Durable functions = code-first workflows. Both run up to a year. Pick the right tool for your workflow type. 💸

Day 14/30 Serverless Best Practices: Step Functions has 1000s of direct AWS integrations. No Lambda, no cold starts, no code. Code-heavy workflow? Try Lambda durable functions instead. 🔌

Day 13/30 Serverless Best Practices: Stop writing Lambda just to route events. EventBridge Pipes from DDB, Kafka, SQS, Kinesis gives you filtering, transformation, and enrichment built in...zero custom code. 🔗 🔗 🎬 youtu.be/tMvwM_KXNPA?...

Day 12/30 Serverless Best Practices: The best Lambda function is the one you don't write. API Gateway connects directly to DynamoDB, SQS, and Step Functions, no cold starts, no code. 🚫

Day 11/30 Serverless Best Practices: One bad record? Don't retry the whole batch. Use ReportBatchItemFailures, only failed records go back to SQS, successful ones are done. 🔧 🎬 youtu.be/tMvwM_KXNPA?...
#Serverless30Days #Serverless
Day 10/30 Serverless Best Practices: Filter before invoke. 450M → 10M messages = 92% cost cut. Content-based filtering stops Lambda ever seeing events it doesn't need to process. 💰

Day 9/30 Serverless Best Practices: SQS + Lambda visibility timeout = 6x function timeout. Always add a DLQ. Miss these and messages disappear silently with no way to recover them. 📋

Day 8/30 Serverless Best Practices: Queues vs. Streams Queues (SQS): single consumer, message deleted after processing. Streams (Kafka/Kinesis/DDB Streams): multiple consumers, replay, order matters. Pick the right one for your use case.. 🔀

Day 7/30 Serverless Best Practices: Store first. Reply fast. Process later. Async breaks the chain — one slow dependency can no longer take down everything else. ⚡

Day 6/30 Serverless Best Practices: Frameworks- SAM,CDK,SST,Serverless,Terraform. Pick one. Any one. Just use a framework. Without IaC, deployments are manual, fragile, and impossible to repeat reliably. 🛠️

Day 5/30 Serverless Best Practices: Don't split Lambda functions prematurely. Start cohesive. Split when it hurts. 42 functions from organic growth = deployment chaos and impossible debugging. 🏗️

Day 4/30 Serverless Best Practices: More memory = more CPU = faster = cheaper. Lambda bills by duration × memory — so faster execution can offset the higher rate. Use Power Tuning to find your sweet spot. 💡

Day 3/30 Serverless Best Practices: One Lambda. One job. Split only when it hurts. A function doing five things is five debugging nightmares waiting to happen. 🎯

Day 2/30 Serverless Best Practices: 6s processing. 3% failures. 23% abandoned. Issues can add up without best practices & and every one is easily fixable with knowing some simple architecture. ⚠️
