Building Enterprise Clouds: Reset Expectations To Get Them RightAlessandro Perilli General Manager, Open Hybrid Cloud, Red Hat @giano

When We Think About “Cloud” We Think About:

• Simple • Cheap-ish !

• Self-service • Standardized and fully automated • Elastic (application level) • Resource consumption-based • Infinitely scalable (infrastructure level) • Minimally governed

Reality

What Usually Happens…The (Public) Cloud

!

• Apparently simple • Cheap-ish !

• Self-service • Standardized and fully automated • Elastic (application level) • Resource consumption-based • Infinitely scalable (infrastructure level) • Minimally governed

The (Enterprise) Private Cloud !

• Undeniably complex • Expensive !

• Self-service • Partially standardized and barely automated • All but elastic • Mostly unmetered • Capacity constrained • Heavily governed

COMPLEX AND EXPENSIVE

A (Very Mature) Private Cloud

A Second Opinion

Subbu Allamaraju, Cloud Chief Engineer, eBay: OpenStack is a cloud controller software. Though the community did a nice job at putting together

this software, an instance of an OpenStack installation does not make a cloud. As an operator you will be dealing with many additional activities not all of which users see. These include infra onboarding, boostrapping, remediation, config management, patching, packaging, upgrades, high availability, monitoring, metrics, user support, capacity forecasting and management, billing or chargeback, reclamation, security, firewalls, DNS, integration with other internal infrastructure and tools, and on and on and on. These activities are bound to consume a significant amount of time and effort. OpenStack gives some very key ingredinents to build a cloud, but it is not cloud in a box.

Where Most Enterprises Are

PARTIALLY STANDARDIZED AND BARELY AUTOMATED

It’s Easier Said Than Done…

…And In Fact Most Don’t Do It


ALL BUT ELASTIC

What Does “Cloud Application” Mean Anyway?

CAPACITY CONSTRAINED

MOSTLY UNMETERED

CAPACITY CONSTRAINED

HEAVILY GOVERNED

SO WHAT TO DO?

Nope. Enterprises See Enormous Value in Private Clouds

We created a copy of production and orchestrated new environments every two weeks. We didn't know this in the beginning but the results are there. Speed to market and quality.

!

We looked at two years of infrastructure provisioning demand to come up with [PaaS bundles]. We thought we'd capture 35% of low hanging fruit when we put together initial bundles. We found that those bundles turned into 67% in just over three months. We had no idea that people would adopt the bundles so readily. Had we known that originally it probably would have changed how we went about doing some of those pieces. It was interesting learning, unexpected, and pleasant.


Reset expectations

Select a cloud solution that adjusts to your organization maturity level !

A bundle with 6-12 management modules is overkill (and overpriced)

Don’t believe the promise of a fully automated production cloud !

Stay focused on building a solid dev & test cloud first

Introduce support for scale out application in a meaningful way !

Consider a multi-tier cloud architecture
