Best practices for global enterprises moving to multi-cloud environments: How SD-WAN can help
You have a multi-cloud environment – now what?
Whether they set out to use multiple clouds or not, large enterprises today end up with several cloud suppliers. In fact, it’s probably hard to find a company that isn’t using some mix of Microsoft Azure, Amazon AWS, IBM Cloud, Salesforce.com, Oracle, Google G-Suite, ServiceNow or Box. The list goes on and on. This is more pronounced with enterprises that have a global site footprint.
The cloud, after all, gets you out of the business of hosting applications and worrying about upgrading hardware and software constantly. It also enables you to sidestep the capital commitments otherwise required.
However, the more clouds you use, the more complex connectivity becomes. Security concerns skyrocket as it becomes hard to figure out who is accessing what, from where and how. In addition, the network becomes central to application performance across the organization.
Forces at work
Despite the network challenges multi-cloud creates, multi-cloud is here to stay and will become even more complex with time as:
- Companies turn to even more SaaS offerings that enable them to embrace best of breed rather than multi-purpose on-premise solution bundles that have to meet various requirements of legacy environments
- Technologies, such as serverless computing and other advances, that are only possible with cloud native applications attract more enterprise workloads
- Adoption of Internet of Things technologies and strategies require organizations to collect and analyze data closer to scattered sensors at the edge of the network, probably in specialized cloud services
- Companies try to mesh cloud tools with on-premises systems in hybrid configurations because stringent security or compliance requirements – or the tightly integrated nature of those legacy systems – prevents going all in with cloud
Unfortunately, this shifting, demanding and dynamic environment is not a good fit for the 20-year-old legacy MPLS wide area networks that many organizations still rely on. Besides the fact that MPLS simply can’t provide off-ramps to many cloud tools, adding bandwidth is expensive and simple network changes can take months. It’s like trying to erect a shiny new skyscraper on a stone foundation fit for a mountain cabin. Businesses are short changed on time to market and this is a big no for CxOs driving WAN transformation initiatives.
The good news is software defined-WANs promise agility and enable enterprises to realize the full potential of what multi-cloud environments have to offer. But traditional SD-WANs don’t own the network and have to partner with telcos and service providers that do, creating a suboptimal solution. This is where a fully managed SD-WAN solution, where the provider owns both the network and the software definition provides the “best of both worlds.”
A fully managed SD-WAN running on a private network can connect far-flung employees to various data centre resources while also providing direct connections to public cloud platforms such as AWS, Azure, Google and Oracle as well as connectivity to SaaS platforms such as Office 365, Salesforce, WebEx and Zoom, without compromising on application performance.
A managed SD-WAN allows enterprises to shift higher value human resources from the business of assessing technology, building out the network and then constantly tweaking and optimizing it as requirements change. Patching edge-routers or boxes from traditional, SD-WAN vendors is often an operational nightmare.
When managed SD-WAN is delivered as a service, it is akin to a SaaS provider, delivering connectivity as-a-service.
While SD-WAN services can help any organization deliver consistent application performance to employees around the world, the benefits for IT are magnified in multi-cloud environments because they get a unified view that is cloud provider agnostic.
However, not all managed SD-WAN services are alike. Speed of provisioning new circuits, the reliability of the backbone, the quality of the support and ease of engagement – all make a huge difference! Look for a fully managed SD-WAN that leverages a private network for the middle mile, uses built-in acceleration and optimization tools to improve application performance, and uses best of breed layered security from partners for mission-critical applications.
So, when it comes to looking for an SD-WAN delivered as a service to support growing multi-cloud needs, look for:
- A simple, managed global solution for multi-cloud connectivity
- End-to-end reliability SLAs guaranteeing 99.99% uptime
- 24x7x365 monitoring and CCIE-level support
- Built-in WAN acceleration and optimisation, regardless of the cloud resource targeted
- Off-ramps to all the cloud providers
- Deployment capabilities measured in hours at any site globally
- Support for on-demand site and bandwidth changes
CIOs invest considerably in their public and multi-cloud strategy. The productivity of developers and corporate applications is compromised, if the underlying network connectivity is flaky or if it takes too long for a predictable site connection to be up and running. Digital transformation and the move to the cloud should start with the network. That is ground zero for a multi-cloud world.
