One of the most critical decisions a CTO can make is selecting the cloud environment for his or her company. It is intimidating, complicated and crucially important. When making that decision, it helps to know the attributes of the enterprise-class cloud, the “gold standard” for cloud computing. Here are just a few.
Fully managed and Highly Consultative
By partnering with a leading vendor, you can leverage their IT expertise to architect the high-quality operations, recovery and business continuity processes your organization needs. Their consultative approach helps to protect you from the many vulnerabilities experienced by companies acting without expert guidance.
An enterprise-class cloud is service-rich and supports fully managed operations for both cloud-ready and non-cloud-ready applications (which require dedicated solutions). It comes with a holistic Service Level Agreements (SLA) that covers the complete environment—from performance levels for each component to 24/7/365 support, security, production processes, problem resolution steps and required staff certifications, along with ITIL, ISO9001 and governance procedures.
While the vBlock that underpins most enterprise-class clouds is highly resilient and redundant, it cannot prevent a server from crashing or a power outage from occurring. Consequently, individual vendors are responsible for overall resiliency, whether that means automating failover capabilities or establishing integrated, multi-site, disaster recovery locations. Similarly, vendors must specifically build into their offerings the security to monitor the access, use, disclosure, disruption, modification and destruction of data by users and programs. It will serve you well to question potential vendors diligently about their resiliency capabilities.
Different Expectations for Different Use Cases
Different use cases require different levels of quality (reliability, up time, security, etc). Once you define the requirements for your application, you can determine the price-performance trade offs your company can afford to make. For example, a commodity cloud (like Amazon) offers:
- Unlimited capacity,
- Quick provisioning (turns on fast; shuts off fast. Swipe your credit care and run your job),
- Low cost and lots of control (e.g., root access and API-level access) and self-service.
However, the trade-offs include:
- A weaker security infrastructure,
- Little, if any, technical support (i.e., no consultation on set-up or phone support), and
- No backup or disaster recovery plan except the one you devise and request.
Use cases for Amazon might include a test site or support for a start-up company that needs a cheap development environment with a high degree of control.
By contrast, an enterprise-class cloud (like SunGard’s) offers:
- Consulting to assess and deploy applications wisely,
- High-quality security, uptime and compliance,
- High levels of customer support,
- A service-rich environment,
- Fully managed operating system and VMware for provisioning, and
- Architecture with built-in resiliency.
The trade-off for the enterprise cloud is that more time is required to move to the cloud. Use cases include production environments that need security and compliance capabilities.
Not all clouds are created equal. It pays to ask questions about every aspect of the cloud environment, carefully identify your company’s needs and match them to the capabilities of the vendor and make sure your SLA spells out the service levels you expect.
