ArquiteturaVantagens Nuvem
Technical● Automation – “Scriptable infrastructure”● Auto-scaling● Proactive Scaling● More Efficient Development lifecycle● Improved Testability● Disaster Recovery and Business Continuity● “Overflow” the traffic to the cloud
Business● Upfront infrastructure investment● Just-in-time Infrastructure● More efficient resource utilization● Usage-based costing● Reduced time to market
ArquiteturaCloud Best Practices
1. Design for failure and nothing will fail2. Decouple your components3. Implement elasticity4. Think parallel5. Keep dynamic data closer to the compute
and static data closer to the end-user
1. Design for failure and nothing will fail
Exemplo Táticas● Elastic IPs● Multiple Availability Zones● Multiple Regions● Amazon Machine Image● Amazon CloudWatch● Amazon EBS● RDS - Automated Backups
5. Keep dynamic data closer to the compute and static data closer to the end-user
