Public Cloud
• Global Footprint• Massive Scale• Extreme Velocity
Vendors
Advantages
Challenges• Stability• Security• Privacy
• End-to-End Network
• Security & SLA • App QOS
• SI Capabilities• Enterprise Trust• SMB Channel
Managed Cloud SP/SI Cloud
• Higher price than Public Cloud
• Limited services capabilities
• Agility
• Stack lock-in• Not always best of
breed for whole stack
Containers • Lightweight Linux execution environment• Static application composition • Reliable deployment • Unit of resource isolation • Execution isolation • Multi-tenancy without heavyweight VMs

Cloud 2.0 Where Awesome Happens

“…the future of technological innovation is not stealing limited resources away from one another, but creating new resources — and new opportunities to create new resources — together in a rich ecosystem.”

“A design pattern in which software/application components provide services to other software/application components via a protocol, typically over a network and in a loosely-coupled way.”
SOA Definition circa 1995
Componentization

“In computing, microservices is a software architecture style in which complex applications are composed of small, independent processes communicating with each other using language-agnostic APIs.These services are small, highly decoupled and focus on doing a small task, facilitating a modular approach to system-building.”
Microservices
2015 – Service proliferation
Alex Williams (the New Stack) : Looking out at 2015, what are some of the issues that will be more complex in this distributed infrastructure world for customers – what are some of the top ones you see?
Mitchell Hashimoto(Hashicorp) - Number one is service proliferation, where your data center just becomes more and more services. Number two is, inherently becoming multi-data-center and highly-distributed at a much earlier stage. With things like Docker, where you can run things in much smaller units, it becomes a lot easier to start running a lot more services. As a result, we have a management problem, an orchestration problem, and distributed system problems in there.

The Zombie Problem
Public Cloud – Utility Computing
• Massively Scalable
• Secure
• Competitive Prices
• Portability
• Distributed Applications
• Proliferation of Microservices coming
Private Cloud – Minimum Viable Cloud
• Cloud Tenets(Rapid Elasticity, Metered, Self-Service, Pooling, Broad Network)
• Hosted on User Selected Hardware• Tailored to just what you need• Unlikely to have less zones then public clouds• Next evolution of cloud isn’t all-in-on, it’s
federation of cloud services (no silos)
Public Cloud Plus – Services/Network/Hardware/Mgmt• Minimum Viable Cloud• Network Quality of Service*• Application Management *• Service Level Differentiation*• Developer Environments*• Advanced Security*• Continuous Integration*• Developer Environments *
