Editor's Notes
- Lead Architect Australia and New Zealand AWS Advanced Consulting Partner Wide range of Clients from Suncorp through to Fed and State Govts Specialising in Open Data portals throughout Australia. Heading up new office in Auckland NZ.
- An age old issue for business has been scale versus agility. SMBs often have Agility and Enterprise Scale. Barriers to scale are cost. Barriers to agility are compliance. Cloud offers an elegant solution to both these issues.
- Over the last 30 years we’ve moved from desktops to the cloud. Throughout this time period we’ve been accustomed to single, identifiable assets; often treated as pets. In order to scale it’s vital to transcend this pet mentality. The cloud mantra is cattle not pets.
- Cloud offers us low cost, agile, secure environments that are easy to manage. These features solve a lot of issues IT has traditionally faced, such as single pane of glass management. Cloud offers a holistic view of assets complete with monitoring, security etc.
- To scale we need centralised user and asset management Standardised provisioning via orchestration suites Automated application deployment and environment management
- Consolidated billing centralises resource management. It facilitates standard provisioning by allowing the same template parameters across multiple accounts. Not possible with a single account. It ensures a robust security model via role switching SMBs often don’t think about management at scale until it’s too late
- Orchestration allows Enterprise to enforce standards and SMBs to develop standards. CloudFormation Templates build OpsWorks stacks OpsWorks stacks create a standard maintainable build Testing and Improvements can be baked back into the standard templates Version control facilitates auditing and control
- AWS CloudWatch monitoring triggers scaling events and alerts AWS Autoscaling groups allow scheduled scaling policies to control cost ASG facilitates load based policies to manage unexpected high demand ASG also maintains environment health by automatically replacing unhealthy instances
- With the right tools, application maintenance is possible using Continuous Integration. Developer changes can be automatically pushed to UAT, and once accepted, deployed to production using web hooks. Use OpsWorks Blue Green stacks with ELB to roll out production changes safely
- Start and improve over time. The ideal system can’t be built in a day. Always ask yourself, “Will it scale?” Aim for continuous improvement continuously!
