Knowing the Caveats in Cloud Computing

Cloud computing has become such a buzzword in business circles today that many organisations both small and large, are quick to jump on the cloud bandwagon – sometimes a little too hastily.

Yes, the benefits of the cloud are numerous: reduced infrastructure costs, improved performance, faster time-to-market, capability to develop more applications, lower IT staff expenses; you get the picture. But contrary to what many may be expecting or have been led to believe, cloud computing is not without its share of drawbacks, especially for smaller organisations who have limited knowledge to go on with.

So before businesses move to the cloud, it pays to learn a little more about the caveats that could meet them along the way. Here are some tips to getting started with cloud computing as a small business consumer.

Know your cloud. As with anything else, knowledge is always key. Because it is a relatively new tool in IT, it’s not surprising that there is some confusion about the term cloud computing among many business owners and even CIOs. According to the document The NIST Definition of Cloud Computing, cloud computing has five essential characteristics, three basic service models (Saas, Paas and Iaas), and four deployment models (public, community, private and hybrid).

The first thing organisations should do is make a review of their operations and evaluate if they really need a cloud service. If they would indeed benefit from cloud computing, the next steps would be deciding on the service model that would best fit the organisation and choosing the right cloud service provider. These factors are particularly important when you consider data security and compliance issues.

Read the fine print. Before entering into a contract with a cloud provider, businesses should first ensure that the responsibilities for both parties are well-defined, and if the cloud vendor has the vital mechanisms in place for contingency measures. For instance, how does the provider intend to carry out backup and data retrieval operations? Is there assurance that the business’ critical data and systems will be accessible at all times? And if not, how soon can the data be available in case of a temporary shutdown of the cloud?

Also, what if either the company or the cloud provider stops operations or goes bankrupt? It should be clear from the get go that the data remains the sole property of the consumer or company subscribing to the cloud.

As you can see, there are various concerns that need to be addressed closely before any agreement is finalised. While these details are usually found in the Service Level Agreements (SLAs) of most outsourcing and servicing contracts, unfortunately, the same cannot be said of cloud contracts.

Be aware of possible unforeseen costs. The ability of smaller companies to avail of computing resources on a scalable, pay-as-you-go model is one of the biggest selling points of cloud computing. But there’s also an inherent risk here: the possibility of runaway costs. Rather than allowing significant cost savings, small businesses could end up with a bill that’s bound to blow a big hole in their budget.

Take for example the case of a software company cited on InformationWeek.com to illustrate this point. The 250-server cluster the company rented from a cloud provider was inadvertently left turned on by the testing team over the weekend. As a result, their usual $2,300 bill ballooned to a whopping $23,400 over the course of one weekend.

Of course, in all likelihood, this isn’t going to happen to every small and midsize enterprise that shifts to the cloud. However, this should alert business owners, finance executives, and CEOs to look beyond the perceived savings and identify potential sources of unexpected costs. What may start as a fixed rate scheme for on-demand computing resources, may end up becoming a complex pricing puzzle as the needs of the business grow, or simply because of human error as the example above shows.

The caveats we’ve listed here are among the most crucial ones that soon-to-be cloud adopters need to keep in mind. But should these be reasons enough for businesses to stop pursuing a cloud strategy? Most definitely not. Armed with the right information, cloud computing is still the fastest and most effective way for many small enterprises to get the business off the ground with the lowest start-up costs.

Carbon emissions reduction has evolved beyond simply good citizenship to being a business tool. Implementing ?green? initiatives is now a competitive weapon which defines real business opportunities and bottom line savings that can contribute significant financial value to the organisation while meeting demanding customer requirements for sustainable and low-carbon products.

Energy efficiency is a low cost resource for achieving carbon emissions reduction. Better energy efficiency simply translates to lesser carbon emissions and less energy usage which translates into saved costs.

Reduction of an organisations carbon footprint is each and everyone?s responsibility. Human activities are the key responsibility for the release of greenhouse gas emissions into the atmosphere. These include usage of electricity generated from fossil fuel, heating or driving.

At the corporate level, various measures can be instigated to increase energy efficiency. Some of these can be, having zone lighting with sensors to minimise unnecessary office lighting, timers on large IT equipment, promoting energy efficient behaviour in the office, asking staff to switch off and unplug appliances when not in use and minimising staff travel.
At the individual level; it is the small habits that count; cultivating the habit of switching off unnecessary lights, plugging out appliances that are not in use, using video conferencing or online chatting instead of having to travel to meetings, using public transport instead of taking a taxi/ personal car and using energy efficient cars.

All these initiatives assist organisations in their corporate social responsibility reports and play a role in sustainability rankings which is instrumental to customers who are increasingly considering sustainability rankings in investment decisions, while achieving the goal of cost reduction internally.

The Future is Smarter with a Smart Meter

Traditionally, electricity and water meter consumption was measured via analogue meters. Utility billing was based on actual consumption units obtained from the meter by meter readers. This entailed physical visits to the metering point. Lots of challenges came with meter reading; talk of customers feeling their privacy is intruded, meter readers encountering hostile customers, dogs, closed gates. The result was estimated bills that were most often than not very high.

Smart meters can be dubbed as the ?next generation? type of meters. Smart meters send wireless electronic meter readings to one?s energy supplier automatically. There are both gas smart meters and electricity smart meters. Smart meters come with in-home displays, which give someone real-time feedback on their energy usage and the associated cost.

Smart meters communicate meter readings directly to utility companies therefore no one has to come to your home to read your meter; and neither are you required to submit meter readings yourself. This not only reduces costs, but leads to more accurate electricity bills practically eliminating estimated bills. Smart meters signal the end of estimated bills, and the end of overpaying or underpaying for energy.

Whereas a smart meter in itself does not save you money, the add-ons (in-home displays) that come with the smart meters and which give someone real-time feedback on their energy usage helps them to reduce the unnecessary energy use and this ultimately leads to better oversight into how to lower utility bills hence better management of one?s energy use.

In summary, a smart meter is a technology that enables energy consumers to see their energy as they use it, a technology where energy is displayed as it is being used and wireless ratings sent. Adoption of smart meters would mean the end of estimated energy bills.

Smart meters are also promising a smart future where all energy consuming devices can be connected to the internet and centrally controlled using computers or smartphones. This means one is able to switch off lights and other energy consuming devices from a central point, hence make savings and this will enable them to have greater control of their energy use, hence more comfort, convenience and life will be cheaper for all. This is the smarter future we are all looking forward to.

Authentication and Access Control

Threats to your data can come from external or internal sources.

  1. There are individuals who don’t have the authorisation but are driven by malicious intentions to gain access to certain information. This may refer to individuals who already belong to your organisation (but don’t have the necessary access rights) as well as those who don’t.
  2. There are individuals who have both the authorisation and, unfortunately, the malicious intentions over certain information.
  3. Finally, there are individuals who have the authorisation, no malicious intentions, but have accidentally exposed the information in question to those without the proper authority.

While curbing threats 2 and 3 would require other methods, threat #1 can be countered if the right authentication and access control systems are in place.

Here’s what we can do for you:

  • Work with your key personnel to determine who gets access to what.
  • Help you decide whether a single factor or a two-factor authentication (2FA) is appropriate for your organisation and recommend which factors are most suitable. Login methods may include but are not limited to the following:
    • biometric devices
    • Kerberos tickets
    • mobile phones
    • passwords
    • PKI certificates
    • proximity cards
    • smart cards
    • tokens
  • Install the necessary infrastructure needed for the factors chosen. For instance, if you opt to use biometrics, then biometric scanners will be installed. We’ll make sure that the authentication terminals are situated in places where achieving optimal traffic and work flow has been taken into consideration.

Other defences we’re capable of putting up include:
