Design Considerations
Core focus and need varies by industry Yet there are core commonalities across all industries
SoftLayer, an IBM Company
Key design considerations Performance and scalability is achieved through solid design
Why is scalability so hard? It can’t be an after-thought. It requires applications and platforms designed with scaling in mind. Is achieving good scalability possible? Absolutely, but only if we architect and engineer our systems to take scalability into account. Simply throwing additional CPU cycles or storage at an application is not going to deliver linear scalability unless the application was designed to scale in such a manner.
SoftLayer, an IBM Company
Stateless and async. One of the guiding principles for linear scalability is to have lightweight, independent, stateless operations that can be executed anywhere and run on newly deployed threads/processes/cores/machines transparently as needed in order to service an increasing number of requests. Share nothing. Testing async code can be non-trivial. Test coverage should be pursued early (as in at the start). Test early, test continuously.

Key design considerations Performance and scalability is achieved through solid design
Eliminate choke points. Everything that has to be coordinated by a single machine, or even a single cluster, is a failure waiting to happen. I/O constraints. Typically network and storage. Architecture, design, and/or implementation flaws. Try to find them intentionally, not accidentally. Expect failure. Distributed applications and services are comprised of a lot of moving parts, each of which are prone to fail in their own way. Understand the potential failure points and architect your mission critical resources to survive.

The Future.. Is Now
• Linux Containers (LXC à LinuX Containers) – Lightweight virtualization – Realized using features provided by a modern Linux kernel – VMs without the hypervisor (kind of)
• Containerization of – (Linux) Operating Systems – Single or multiple applications
• LXC as a technology is not the same as LXC “tools”
Linux Containers (LXC) Bringing a new level of performance, agility, and ease-of-use

Summary
• Cloud Adoption – Enterprise applications versus Internet scale applications – Key verticals innovating with, and driving innovation in, the cloud
• Key Considerations – Many factors ultimately determine success in the cloud – Realize the potential of cloud when you architect for the cloud
• Cloud Architectures – We supply all the building blocks, you bring the blueprints – Open yourself to all of the possibilities cloud enables
• Future (is now) – Evolving at a rapid rate – Embrace all aspects of cloud – from infrastructure to platforms to services
Summary How To Architect and Optimize Your Cloud for Consistent Performance
