Last week’s AWS outage reminded us of two valuable lessons. The first is that AWS plays a large role on the internet, as many popular sites and services were impacted by the issue. The second is that as our dependency on the cloud continues to rise, companies would be well-served to have multiple providers.
This opinion was echoed in an article in InfoWorld in which columnist Andrew Oliver advocated for the benefits of having redundant infrastructure. In his column, Oliver wrote that it has never been easier or less expensive to ensure redundancy:
But today’s database technology, microservices architecture, and vastly improved software make redundancy much cheaper and easier. But don’t get hung up on using only one provider’s offerings.
In an article on MSPmentor, Aldrin Brown addressed some of the additional benefits of a multi- or blended-cloud approach,
By mixing and matching workloads with the ideal cloud vendor and best price, organizations can maximize the cost, agility and security benefits of cloud computing.
We agree with the above mentioned benefits and also understand first-hand that, despite best efforts, no vendor is perfect. This is why we have long advocated the benefits of multiple providers at every layer of your infrastructure, including your DNS.
One of the challenges in a multi-cloud strategy is: how do you manage traffic between your multiple clouds? The answer is one of the inspirations behind our “Rethink DNS” concept. Too many people think of DNS in a vanilla fashion. They set it and forget it.
However, you need to rethink DNS. DNS has a hidden value in that it is an excellent way to steer traffic between multiple clouds, which ensures the highest performance possible. It does this by using Global Load Balancing. Many companies, such as Evernote, are using load balancing in their migration to cloud. But they shouldn’t stop there. Using load balancing to navigate between cloud providers means that you will benefit from all the cloud has to offer without ceding control or finding yourself in a vulnerable situation. Multi-cloud is the future and DNS is the path to get there.
