Redundancy in the Cloud

Somehow, a perception exists that a cloud provides a certain level of redundancy by default. However, make no mistake. Redundancy is not inherent. Admittedly, individual hardware and software components have some redundancy built in. However, those capabilities do not eliminate the need for a redundant cloud any more than safe cars eliminate the need for speed limits, traffic lights, divided highways and the rules-of-the-road. For many cloud providers, especially consumer cloud providers, the only redundancy offered is to make physical copies of the data—and many customers do not use even that minimal level of recovery.  These clouds were not built with redundancy in mind.  They lack the au … Read more

Business Continuity in the Cloud

Business continuity focuses on the resiliency, restoration, disaster recovery and security needed to keep your system operating, performing, secure and, if an incident should occur, recoverable. Many cloud vendors have little experience with business continuity, preferring instead to offer consumer cloud services to clients that provide their own back-up procedures, intrusion protection, vulnerability alerts, firewalls, software upgrades and disaster recovery planning/testing. Resiliency is the key Without strong resiliency, redundancy and failover capabilities at each layer of the cloud stack, the failure of one component can cause the  failure, in short order, of many subsequent … Read more

Should you Negotiate your SLA?

Solutions Marketing Manager Janel Ryan discusses service level agreements today. –  Carl M Much has been written in the few months about negotiating a better Service Level Agreement (SLA) with your cloud vendor.  Before you follow that advise, you may want to consider a few key points. Be Realistic First, If you are going to negotiate with your cloud provider, you have to be realistic about the performance you need and you have to be prepared to pay for those services. No vendor is going to take on more responsibility without charging more, no matter how hard you press. Review the Architecture Second, you’ll need to determine whether the vendor is capable of providing the service or per … Read more

Understanding the Impact of Multi-Tenancy Design Concepts

Understanding the Impact of Multi-Tenancy Design Concepts Today we hear from Chip Childers, product architect for SunGard’s Enterprise Cloud Services and partners with our product management and product engineering teams to drive the overall solution design of the service...CM As you evaluate different cloud providers, it is important to understand the different concepts providers can use to deploy multi-tenancy.  Different concepts facilitate—or limit—the way in which a provider can respond to changes in the service needs of clients. General Purpose Clouds For example, some vendors design their clouds as commodities.  They focus on providing low cost access to computing power in  homoge … Read more

Cloud is a Service, Not a Commodity

Forrester’s James Staten recently wrote a very well written (and widely read) piece on Cloud Computing trends for 2011.  While I agree with most of his bold points and predictions, one point gave me pause.  James writes: “Cloud economics gets switched on.  Being cheap is good. We all know the basic of cloud economics — pay only for what you use — but the mechanism isn’t the lesson; it’s just the tool. Cloud economics 101 is matching elastic applications to cloud platforms and moving transient apps in and out so their costs are constantly returning to zero. Cloud economics 201 is designing and optimizing applications to take greatest advantage. Cloud economics 301 is knowing when and which cl … Read more

Can Cloud Computing Improve Your Security?

Cloud Security continues to dominiate the cloud conversation.  I asked Nik Weidenbacher, director of product engineering for cloud computing to give us his thoughts on cloud improving security.  Nik and his team are responsible for designing, building and testing the infrastructure for SunGard’s Cloud Computing Service...CM Can Cloud Computing Improve Your Security? Obviously, the answer is “it depends.”  How good is your security now?  A number of factors play into that question. Security in a Data Center If your technology runs in a traditional data center and you move to a cloud where the same technology is used, security is quite similar.  Essentially, you’ve been using virtual local … Read more

Is the Cloud Security Risk Overstated?

Gregory L. Smith, Senior Product Architect for Cloud Computing, is a liaison to clients for defining and shaping the security components of SunGard’s Cloud Computing Services. Is the Cloud Security Risk Overstated? Is the cloud security risk overstated?  If you work with a trusted partner and already have good security practices in place before you move to a cloud, I think the security risk in the cloud is slightly overstated.  It is not cloud computing itself that is the risk. The Security Risk Realization Unfortunately, it is not uncommon for a company to be planning a move to a cloud and suddenly see risks everywhere, including places that they had naively overlooked in their existing env … Read more
