IT Challenges 

Major issues with traditional infrastructure

Our data is too large
• Volumes of data are being generated at unprecedented levels
• Most of this data is unstructured
• Service requests are too large
• More and more devices are coming online
• Tablets, phones, laptops, BYOD generation…
• Crucially, applications weren’t written to cope with the demand!
• Traditional infrastructure capabilities are being exhausted
• Service uptime, QoS, KPI’s and SLA’s are slipping

What is a cloud workload ?

 

 

  • There are many types of workloads in the datacenter, solution must serve all of them
  • Pets or cattle? Lots of pets, lots of cattle too
  • Portability – environment has to be portable
  • Solution needs to be highly available and reduce/eliminate single points of failure
  • Create an efficient system to allow repeatable and auditable processes
  • Needs to meet corporate security and compliance requirements
  • Ability to charge back the LOBs
  • Support for IPv6

Which emerging technologies and standards are most important to watch

• Inefficient utilization of resources.
• Resource saturation.
• Lack of elasticity and scalability.
• Lack of security and governance.
• Frequent outages.
• Bad or no tenant management.
• Other very bad things.

Use Cases for OpenStack Today
Main use cases:

DevOps – important to move content from dev to ops quickly
Software development – test environment, ability to bring up and tear down sophisticated topologies and configuration
Elasticity/scalability – users who need to burst and gain large scale quickly
Batch processing/HPC
Web companies –
NFV
Early Adopters:
Small groups
Strong IT skills set can “figure stuff out”
Fairly simple regulatory environment
