The cloud has had a profound impact on countless areas of IT in recent years, but nowhere has it been more of a game-changer than in the field of Disaster Recovery (DR).
Many companies don’t manage to focus on DR, as they perceive it to demand time and money which they have invariably consumed elsewhere, and thus take a ‘risk’ that is actually more of a ‘gamble’.
Cloud-enabled SQL Server DR is more economical than traditional methods, as there is no lead-time or capital outlay; there is no need for businesses and organisations to buy additional hardware, network resource, data centre storage or to have dedicated personnel. This is all combined in one cost-effective monthly subscription.
The cost of downtime can run into tens of thousands of pounds per hour, depending on the size of the business. It makes financial sense to think about disaster recovery proactively. Cloud now makes SQL Server DR accessible to companies which historically wouldn’t have been able to afford it in the past.
Utilising Cloud SQL Server DR enables businesses to:
dsp have extensive experience of using cloud for Database DR and are perfectly placed to advise you on the issues you need to consider when evaluating it. This includes network considerations around bandwidth, security, latency, and issues around appropriate licensing and cost models.
Effective disaster recovery in the cloud provides continuity for services and the ability to fail over to a second site if there is a hardware or software failure. Workloads can be restored to their original locations when the disaster event is resolved.
At dsp, database uptime is something very close to our hearts and we agree SLAs with clients that guarantee to minimise disruption. There are many ways of managing data recovery, depending on what is right for your needs.
There are a number of important considerations around Cloud SQL Server DR. DSP will help you understand the following:
There must be enough throughput capability between the primary site and the cloud to ensure data can be replicated without too much lag, and also to be able to recover data back to the primary site once the issue is resolved.
Transferring data to the cloud is outside the protection of the private network, so must be encrypted in flight. DSP also ensure data is encrypted at rest. This must be managed to ensure that the process of encrypting does not interfere with operations.
Increased latency as a result of running applications from the cloud rather than onsite may cause performance problems. If only part of a service is migrated into Disaster Recovery, issues can be experienced in intercommunication between on and offsite.
As workloads are moved to the cloud, IP addresses will change. Moving an application to the cloud will require changes to DNS (to point to the new server or data location) and usually modification to the application itself.
Cloud can add great complexity to licensing issues. With our considerable experience and understanding of cloud, DSP can guide you through the relevant compliance mandates and licensing implications to ensure your environment is entirely compliant.
It’s often said that we now live in a data-age rather than merely a digital-age, and that “data is the lifeblood of a company”. With such considerations in mind, effective disaster recovery services can make the difference between an incident being inconvenient, or being catastrophic.
DSP are specialists in SQL Server DR and have a long list of references to support this. In providing a SQL Server DR as a service offering that goes beyond expected standards, not only do we make it time efficient, but we also make it cost-efficient.
If you have any questions on how SQL Server Disaster Recovery can be integrated into your company we’d love to hear from you.
