Cloud Deploy

Cloud Deploy nima?

Cloud Deploy - bu ilovani cloud infrastructure'ga joylash, uni foydalanuvchilarga yetkazib berish jarayoni. Bu "From Code to Cloud" sayohatining oxirgi va eng muhim bosqichi.

Cloud deployment quyidagilarni o'z ichiga oladi:

• Infrastructure provisioning - serverlar, network, storage yaratish
• Application deployment - kod/container'larni serverga joylash
• Configuration - environment variables, secrets, DNS
• Scaling - load'ga qarab resurslarni oshirish/kamaytirish
• Monitoring - sog'liqni kuzatish, alerting

Nega kerak?

Nima uchun o'z serveringizni emas, cloud'ni ishlatish kerak?

Asosiy tushunchalar

Cloud Service Models

• IaaS (Infrastructure as a Service) - VM, network, storage. EC2, Compute Engine.
• PaaS (Platform as a Service) - runtime environment. Heroku, App Engine, Elastic Beanstalk.
• SaaS (Software as a Service) - tayyor dastur. Gmail, Salesforce.
• FaaS (Function as a Service) - serverless. Lambda, Cloud Functions.

Deployment Strategies

Container Orchestration

Containerlarni boshqarish uchun:

• Kubernetes - industry standard, powerful, murakkab
• ECS/Fargate - AWS native, simpler
• Cloud Run - GCP serverless containers
• Azure Container Apps - Azure serverless

Cost Optimization

• Reserved Instances - 1-3 yillik commitment = 30-70% tejash
• Spot/Preemptible - keraksiz capacity = 90% tejash (lekin to'xtatilishi mumkin)
• Right-sizing - ortiqcha katta instance ishlatmang
• Auto-scaling - faqat kerak bo'lganda resurs
• Serverless - idle vaqtda to'lov yo'q

Eng ko'p uchraydigan xatolar

Best practices

• Multi-AZ va multi-region deployment - high availability
• Infrastructure as Code - Terraform, Pulumi. ClickOps yo'q
• Immutable deployments - server'ni patch qilmang, almashtiring
• Auto-scaling - CPU/memory/custom metrics asosida
• Cost tagging - har bir resursga tag (team, environment, project)
• Backup va disaster recovery - RTO/RPO aniqlang, test qiling
• Least privilege IAM - faqat kerakli permissionlar
• Encryption everywhere - at rest va in transit
• GitOps - ArgoCD, Flux bilan declarative deployment
• FinOps practice - cloud cost management culture
