DATA CENTRE PREDICTIONS In order to prepare the network for Digital Transformation, it has to be both customised to fit your organisation’s needs and be flexible enough to adapt when those needs change. JR Rivers, Co-founder and CTO, Cumulus Networks Therefore, a company’s success is linked to how nimbly they can develop and deliver applications that facilitate engagement and business outcomes. If applications are the lifeblood of today’s organisations, networks are the digital nervous systems that support and deliver those applications. The problem is, while application architectures and development methods have become more agile, the traditional data centre network has not kept pace. A new approach to operational efficiency According to Gartner, ‘the top networking challenge… is improving agility’. This, of course, is not a big surprise. What is surprising is Gartner’s advice to ‘pick how you want to manage your data centre network first, then pick the vendor/products that can slot into that decision’. This means that the answer to improving your organisation’s network speed and agility is not necessarily by buying expensive, proprietary monster switches and premium automation solutions. Instead, modernisation starts with IT and network operations which can be achieved through network automation, greater overall visibility into the network and IT- as-a-Service models. A conventional ‘one size fits all’ approach to networking just doesn’t work in the cloud era. 18 Issue 05 Naturally, each networking vendor presents their solution as having the beefiest hardware and the most cutting- edge software. They can make that claim because often they will make both the hardware and software work together flawlessly. But hidden in the midst of this seemingly unbeatable combination is a problem: although the tight coupling of hardware and software by the same manufacturer may ensure compatibility, it kills flexibility. If your network’s hardware and software is inflexible and cumbersome, it will always be a hindrance to agility. No matter how dedicated your network team is, they can’t change the underlying architecture of a vendor’s solution. That’s why it’s crucial for your organisation to adopt a solution that enables you to scale and automate your network. they would scale up or scale vertically to meet performance requirements. That’s not necessarily unreasonable. But when taking the vertical scaling IF APPLICATIONS ARE THE LIFEBLOOD OF TODAY’S ORGANISATIONS, NETWORKS ARE THE DIGITAL NERVOUS SYSTEMS THAT SUPPORT AND DELIVER THOSE APPLICATIONS. The importance of scalability Network scalability means growing the data centre network in proportion to your organisation’s needs. There are different levels of scalability, as well as different ways to achieve it. For example, if an organisation has to triple network spend to double capacity and performance, the network isn’t very scalable. But if they reverse the numbers – double the network spend and triple capacity and performance (and do so quickly) – the network is highly scalable. The level of scalability the organisation can achieve depends on the underlying network architecture. Each organisation must decide whether to scale vertically or scale horizontally. While this might sound like a topic that IT geeks debate over a cup of coffee, it’s a decision that creates a ripple effect throughout the rest of the organisation. Traditionally, if an organisation has been unsure about which particular switch model will be beefy enough to meet its growth needs, it has opted for the larger (and more expensive) one.
