Six unexpected challenges of cloud

For years now there has been talk of how business is driving IT to move to cloud.

In many cases, business teams go so far as to circumvent IT and buy cloud services themselves, taking decisions into their own hands. Much has also been written about why IT should eagerly accept this imperative and embrace the use of cloud.

Why Cloud computing?

Today there are many good reasons why IT should be pushing for cloud, not just for those super-innovative new business-led projects, but for existing, run-of-the-mill IT operations. However, the promise has traditionally touted less work for IT. Many times, it is characterised as a commodity and positioned as a rapid path toward innovation. In general, IT expects cloud to have fewer boxes to maintain, fewer hypervisors to operate, and even fewer purchasing decisions to make.

In reality, however, managing a cloud footprint is much harder and more specialised than many imagine. These services must be selected, workloads must be migrated and usage must be tracked. Not unlike other complex IT systems, these infrastructures have to be monitored and managed, and cloud’s much touted ‘easy scalability’ depends on specific infrastructure capabilities and a watchful eye to identify and correct problems.

Obstacles of Cloud Computing

In April 2014, when iland commissioned analyst firm EMA to conduct a global survey on real-world experiences with public cloud providers, 98% of UK respondents reported they experienced at least one unexpected cloud challenge.

Among the survey pool, the vast majority had made some foray into cloud, and what became apparent was that there were six primary areas where companies discovered unanticipated obstacles:

· Pricing (38%) – The top challenge unearthed in the survey indicated that while cost savings may be a key benefit, current pricing models under which they operate are difficult to understand. Organisations therefore need to carefully analyse pricing models and their own IT needs before they commit.

· Performance (38%) – Different clouds are architected with different back ends, and some are more susceptible to ‘noisy neighbour’ syndrome than others. For organisations sensitive to variations in performance this can impact the cloud experience.

· Support (36%) – The realities of support contracts often take companies by surprise. Simple email or ticketing support may only be available to organisations at lower tiers. Companies purchasing higher-end support may still have difficulties getting access to adequate levels of hands-on expertise. Poor or overly expensive support can become a grating factor limiting cloud success.

· Downtime (35%) – Though many perceive cloud to be immunised from outages, the reality is failures can and do happen. It’s important to understand service level agreements and business continuity options.

· Management of Cloud Services (33%) – Just like on-premise systems, cloud services require IT management. However, many cloud vendors focus on technology innovation instead of simplifying cloud service management. The cloud is a new platform to most IT shops and it can take some time to learn.

· Scalability (33%) – A top promise of cloud is scalability, as it is supposed to allow teams to scale up to meet demand and scale down when the peek has passed. However, most companies experience real challenges both in scaling individual workloads and scaling their entire footprint. Knowing when and how to scale is not always straightforward – especially because some vendors require an environment to be shut down and moved in order to get the job done.

Clearly organisations cannot turn their backs on cloud computing as it represents a key tool in the race for innovation and competitive advantage. Indeed, cloud has a way of opening up opportunities for the business, of freeing the company to dream up new products and services, innovate on existing offerings, and lower the cost of experimentation.

Advice when considering Cloud Computing

I would however advise organisations to carefully consider their cloud choices. Select a cloud vendor with live, human support – and pay attention not just to the availability of such support, but also its cost. Your cloud vendor should be a partner to your IT department. Look for a cloud that makes your job easier – a cloud with familiar management metrics, functionality and straightforward pricing.
