Managing Multiple ‘Clouds’ in an Enterprise- A Heterogeneous Lens

….If you are here I assume you already know. Here to: Provide a few perspectives to aid your journey to manage multi-cloud environments in an enterprise setting.

Cloud Provider - Native API’s

1

•  True Cloud Native •  100% Feature Functionality •  New features here first •  Cloud as it was meant to be

Cloud Provider - Native UI

2

•  85% of API Capability •  Platform Integration not immidiate •  Good for provisioning •  Lacks enterprise governance •  AWS way ahead of others


3

•  30% of native cloud capability •  Used by many CMP’s •  Focused mostly on Compute, Object

Storage and LB •  e.g. fog.io, libcloud, whirr, jclouds

Multi Cloud CMP API

4

•  Lots left to be desired… •  IRONY: •  Provider sells you avoidance of cloud

provider lock-in •  …locks you into their CMP product API

instead… •  Most build on OSS Abstraction Libraries •  …like fog.io, dasein, jclouds, libcloud etc.

Multi Cloud CMP UI

5

•  30% of native cloud capability •  Attempts to add governance,

chargeback, CM, access control •  Most do a very poor job of understanding

enteprise needs •  And keeping up with cloud platform

updates


6

•  Enterprise Wide ITaaS, super-set of all. •  Almost every Enterprise has it •  Service Catalog, Service Request &

Provisioning •  Chargeback, Capacity Mgmt, CMDB, Access

Control, Governance •  Newer breed of ITSM tools/ releases with

strong workflow capabilites, AD Integration and highly API driven

<4> Swallow some bitter truths

The enterprise was clearly not on top of mind when public cloud providers built their

offerings…

…enterprise governance …compliance and security …trying to play ‘catch up’ …AWS ahead of the pack

The Multi- Cloud Management Platforms/Broker products today…

…not enterprise ready

…early in their maturity curve …confused in their strategy

…PR noise …AWS centric

Implementing a CMP won’t rid you of native

management interfaces.

It means managing an additional layer and using in

conjunction with.

<10> Give OSS a

Serious Shake

•  Many CMP’s written on top of Open Source Cloud Abstraction Libraries

•  Github full of options •  Avoid the 800 Pound Gorilla

nightmare •  Asgard/Scalr Open Source CMP’s •  Watch out for Red Hat open

sourcing CloudForms

OSS

<11> Culture as a

legitimate tool to manage Multi-

Clouds!

DevOps! …sorry, had to mention it.

Such Buzzword, much culture!

Cloud = Freedom Freedom = Responsibility

Responsibility = Hold Business Units Accountable

… alterna2ve is to engineer the 6 layer burrito and debilitate public

cloud features.

RECAP 1.   Levelset on taxonomy 2.   Rationalize the 6 layer-burrito 3.   Characterize your workloads 4.   Swallow some bitter truths 5.   Decide whats really worth managing 6.   Incl. all stakeholders in CMP choice 7.   Enable the developer not debilitate 8.   Start bottom-up not top-down 9.   Invest in Infrastructure as code first 10.  Give OSS a serious shake 11.  Use culture as a tool for cloud mgmt
