CLOUDS, ANYONE?

TRIVIA:

THE TERM CLOUD COMES FROM THE ICON USED TO REPRESENT NETWORKS OF COMPUTING EQUIPMENT

- CIRCA 1977

KEYWORDS

Bare metal

Virtual Machine

Hypervisor

Cloud Infrastructure

Containers

Container Orchestrator

“Anything” as a Service

    • the physical server(s)
    • a machine inside a machine
    • a manager of virtual machine(s)
    • a “super hypervisor” (more later)
    • a lightweight virtual machine
    • a container hypervisor
    • new computing paradigm

… AND THE CLOUD IS …

Cloud computing is an information technology (IT) paradigm that enables ubiquitous access to shared pools of configurable system resources and higher-level services that can be rapidly provisioned with minimal management effort, often over the Internet. Cloud computing relies on sharing of resources to achieve coherence and economies of scale, similar to a public utility.

TYPES OF CLOUDS

Private

On premises (on your metal)

You need a cloud infrastructure - e.g. OpenStack

​

Public

On someone else’s metal

Mega cloud providers

​

Hybrid

Part public / part private

​

… (A LOT!) MORE ON THIS LATER

PRIVATE & PUBLIC CLOUDS

17 of 35

PRIVATE CLOUD INFRASTRUCTURE

OPEN STACK

Why OpenStack

  • Data privacy
  • Hybrid clouds and multi-cloud environments
  • Open community, no licence fees
  • Use standard APIs
  • Interoperability
  • Avoid lock-in (Amazon Web Services (AWS), Google Compute Engine and Microsoft Azure are proprietary)

Target customer: medium / large enterprise

  • Who wants a more efficient infrastructure for his applications
  • Who wants to build a Private Cloud
  • Who wants to migrate his Private Cloud to OpenStack
  • Who needs Cloud automation
  • Who needs hybrid clouds and multi-cloud environments

FINAL THOUGHTS

32 of 35

DARK CLOUDS

Security

No physical security for public / hybrid clouds

Privacy

Data is on some else’s server

Physical location of data is unknown uncertain

Compliance

Regulation may mandate for on premises management of data

Vendor lock-in

Public cloud provider & services

Private cloud infrastructure
