Perspectives on Cloud Computing for Enterprises

Perspectives on Cloud Computing for Enterprises Cloud computing offers benefits to enterprises that have a practical understanding of its risks and how to manage those risks.

From a customer’s perspective, solid service-level guarantees ("SLAs") are essential. Depending on the type of cloud service, key SLAs include those addressing:

* system availability/uptime;
* configuration change timeliness (including availability of newly ordered resources)--particularly for IaaS;
* application response time and transaction throughput--for SaaS;
* management portal/tools availability/uptime;
* incident response and problem-resolution times;
* service desk performance--particularly for end user adoption and satisfaction for SaaS;
* back up data success rate, and data restoration times where the vendor will host the customer’s production data; and
* customer satisfaction (and its importance increases as the deployment in the enterprise widens).

Meaningful SLAs should trigger material service credits when the vendor misses its performance thresholds. And the customer should not have to ask for credits--the vendor should proactively monitor its performance and automatically issue SLA credits when due. Solid SLAs can also be undermined by overly broad exclusions, including procedural hurdles and liability limits hidden in the fine print.

SLA best practices include escalating credits based on the severity, duration and frequency of service failures, and processes like the following to limit the recurrence of service level failures:

* requiring the vendor to conduct a root-cause analysis of service problems and to implement a corrective action plan at no additional cost to the customer;

* requiring the vendor to escalate chronic or critical service-level problems to its own and the customer’s senior management; and

* giving the customer the right to terminate the agreement for cause (or shorten the term) when performance failures reach defined levels.

For good reason, security is often cited as the primary concern for customers considering cloud computing. The vendor’s security management approach and tools should be evaluated closely. Security vulnerabilities in the cloud can be the result of design defects, poor patch/update management, ineffectual authentication controls, storing and/or transmitting sensitive data without encryption, and inadequate procedures for security incident monitoring, reporting and mitigation.

When evaluating security, consider:

(1) how the vendor addressed security in its design; (2) customer references;
(3) the vendor’s track record;
(4) the vendor's physical and logical security practices, processes and management approaches;
(5) the vendor’s commitment to continuously improve security; and
(6) the vendor's compliance (validated by independent third party audits) with recognized information security standards. Negotiate the right to conduct periodic security assessments and to assign responsibility for security incident detection, reporting, response and mitigation, and include a defined path for management escalation of unresolved security problems.

It is also important to be practical. Demanding levels of security that are not justified by actual risks or that far exceed the customer's own internal capabilities will get you little and lead to poor decisions.

Data Governance
If the vendor will handle enterprise data, it should also demonstrate its data protection, disaster recovery and business continuity capabilities. The service agreement must clearly describe the vendor's obligations to protect the customer's data during its entire lifecycle, and the vendor should be liable for failure to do so. Contract clauses that support mature data governance include provisions that:

* Obligate the vendor to comply with the customer's vendor-facing privacy policies;
* State that the customer owns its data, has access to that data at its discretion, and will receive the data upon the expiration or termination of the agreement in a usable/standard format and medium;
* Identify the vendor's data extraction tools, and include the customer's use of them as part of the base scope of services;
* Describe the parties' responsibilities and liabilities for recovering lost or corrupted data;
* Define the countries where the vendor may (or may not) send or house the customer's data; and
* Require the cloud vendor to encrypt sensitive application data while in transit and at rest.

Technical, legal, and business issues face enterprises that want to use public cloud computing. Those that want to enjoy the cloud's benefits with minimum risk address provider lock in, service performance, security and privacy risks by selecting the appropriate service delivery model for each use case and negotiating service agreements (with capable providers) that get them the protections they need.
