Migrating to the cloud doesn’t have to be a complex task anymore. KABELO MAKWANE, MD of Accenture South Africa’s Cloud First business, explains the ‘Lift and shift approach’.
‘Lift-and-shift’ – the classic approach to cloud migration – means this: take all your existing IT structures, procedures and applications and transfer them to the cloud.
On paper, such an approach seems sensible. Yet, while cloud migration may mean the benefit of eliminating physical hardware infrastructure on the IaaS layer, transferring needless complexity elsewhere can in fact cause a business’s total cost of ownership on the cloud to escalate. More broadly, the speed and effectiveness of any cloud migration is highly ecosystem-dependent; the application landscape forms only one part.
The reason is the amplifying effect of the cloud. Poorly designed or inefficient IT operating models have their flaws emphasised by the as-a-service paradigm. On one hand, this means that if businesses haven’t designed an efficient service management model or built their application sets with an eye on leanness, they may end up spending more to maintain those functions in the cloud. Other ecosystem areas – including governance and management – also require an expert guiding hand when it comes to cloud pivots.
All businesses are likely to witness a degree of change in their IT operating models when undertaking a migration. For one, cloud changes the way people operate within an IT environment. Because of the high degree of automation within the cloud, for example, people are both freed up and required to work at a higher order, both in terms of IT ops and administration.
Given this consideration and others, enterprises need to assess how fast and to what extent they want to rotate to the cloud. Will it be full-on ERP in the cloud? Full CRM in the cloud with mobility? Partial? The growing impetus for enterprises to forward integrate using cloud services is a related consideration. Indeed, the trend is coming to demand increasing attention.
Consider the near-ubiquity of self-service banking apps. Today, we’d say that a financial services provider without one belongs in the stone age. And yet banking apps have been a relatively recent development. Healthcare is seeing similar developments with the rise of wearable tech. The industry is likely to witness the same level of forward integration, requiring consumers to take some degree of responsibility in terms of managing their own health and wellness.
When it comes to the application-level changes cloud-minded businesses undergo during migration, natively cloud apps will be those requiring the least remediation. Others will likely require more rationalisation and consolidation. Hearkening back to the concept of leanness, enterprises often have a large real estate of custom applications spun out by IT over time. Performing analysis and due diligence on the application landscape before a migration is key. Migrations present a good opportunity to do a little spring cleaning.
Integration layers – what we used to call ‘middleware’ – are key here, yet the area has also witnessed something of an overhaul. There are still middleware players – they haven’t gone away; they have just reinvented themselves. When it comes to modernising applications, containerisation allows for application migration without full reengineering. From a DevOps perspective, tools such as Kitkat and Cucumber can help with rewriting applications so that they become cloud ready.
Another key aspect of the migration ecosystem is governance. The sphere may be easy to overlook, yet business need to ask themselves key questions: ‘Do we have a governance model for operating in the cloud? Does it extend to security, risk and identity management?’ In this line, a concept known as shared responsibility is gaining traction. The approach means that enterprises cannot negate their responsibility to secure their applications and data, even if the cloud is more secure than their existing on-premise environment. It’s about a joint effort.
A final ecosystem component is that of cloud service brokerage. Businesses’ habits of consuming federated IT infrastructures and application environments haven’t gone away. Interest in engaging multiple providers is still driven, in some cases, by organisations shying away from vendor lock-in. Alternatively, enterprises may buy different applications for different purposes, informed by their strategy.
When it comes to consuming federated or disparate environments, businesses often require some level of service brokerage. So there is an emerged discipline – within hyperscale cloud particularly – wherein specific boutique outfits are now building brokerage capabilities. The result is that organisations can consume from multiple cloud types on their own terms.
At the broadest level, to be able to fully realise the promise of cloud in terms of speed, efficiency, cost effectiveness, scale and optimisation, capable oversight is required. The result is that cloud management platforms have emerged – many hyperscale cloud providers are now building management capabilities onto their offerings.
AWS’s EC2 platform for example has seen ongoing investment to natively embed functions around identity management and application integration in the cloud and Microsoft Azure Cloud also sees heavy investment in this area as well in order to build native capability. By embedding such tools, it becomes far easier for businesses to deploy cloud applications as extensive knowledge of middleware and integration tools are no longer required.
In sum, effective, cost-effective cloud migration depends on thoughtful deployment on a host of levels – applications, governance, management and brokerage among them. In short, it’s all about leveraging the ecosystem.
Legion gets a pro makeover
Lenovo’s latest Legion gaming laptop, the Y530, pulls out all the stops to deliver a sleek looking computer at a lower price point, writes BRYAN TURNER
Gaming laptops have become synonymous with thick bodies, loud fans, and rainbow lights. Lenovo’s latest gaming laptop is here to change that.
The unit we reviewed housed an Intel Core i7-8750H, with an Nvidia GeForce GTX 1060 GPU. It featured dual storage, one bay fitted with a Samsung 256GB NVMe SSD and the other with a 1TB HDD.
The latest addition to the Legion lineup has become far more professional-looking, compared to the previous generation Y520. This trend is becoming more prevalent in the gaming laptop market and appeals to those who want to use a single device for work and play. Instead of sporting flashy colours, Lenovo has opted for an all-black computer body and a monochromatic, white light scheme.
The laptop features an all-metal body with sharp edges and comes in at just under 24mm thick. Lenovo opted to make the Y530’s screen lid a little shorter than the bottom half of the laptop, which allowed for more goodies to be packed in the unit while still keeping it thin. The lid of the laptop features Legion branding that’s subtly engraved in the metal and aligned to the side. It also features a white light in the O of Legion that glows when the computer is in use.
The extra bit of the laptop body facilitates better cooling. Lenovo has upgraded its Legion fan system from the previous generation. For passive cooling, a type of cooling that relies on the body’s build instead of the fans, it handles regular office use without starting up the fans. A gaming laptop with good passive cooling is rare to find and Lenovo has shown that it can be achieved with a good build.
The internal fans start when gaming, as one would expect. They are about as loud as other gaming laptops, but this won’t be a problem for gamers who use headsets.

Serious about security? Time to talk ISO 20000
By EDWARD CARBUTT, executive director at Marval Africa
The looming Protection of Personal Information (PoPI) Act in South Africa and the introduction of the General Data Protection Regulation (GDPR) in the European Union (EU) have brought information security to the fore for many organisations. This in addition to the ISO 27001 standard that needs to be adhered to in order to assist the protection of information has caused organisations to scramble and ensure their information security measures are in line with regulatory requirements.
However, few businesses know or realise that if they are already ISO 20000 certified and follow Information Technology Infrastructure Library’s (ITIL) best practices they are effectively positioning themselves with other regulatory standards such as ISO 27001. In doing so, organisations are able to decrease the effort and time taken to adhere to the policies of this security standard.
ISO 20000, ITSM and ITIL – Where does ISO 27001 fit in?
ISO 20000 is the international standard for IT service management (ITSM) and reflects a business’s ability to adhere to best practice guidelines contained within the ITIL frameworks.
ISO 20000 is process-based, it tackles many of the same topics as ISO 27001, such as incident management, problem management, change control and risk management. It’s therefore clear that if security forms part of ITSM’s outcomes, it should already be taken care of… So, why aren’t more businesses looking towards ISO 20000 to assist them in becoming ISO 27001 compliant?
The link to information security compliance
Information security management is a process that runs across the ITIL service life cycle interacting with all other processes in the framework. It is one of the key aspects of the ‘warranty of the service’, managed within the Service Level Agreement (SLA). The focus is ensuring that the quality of services produces the desired business value.
So, how are these standards different?
Even though ISO 20000 and ISO 27001 have many similarities and elements in common, there are still many differences. Organisations should take cognisance that ISO 20000 considers risk as one of the building elements of ITSM, but the standard is still service-based. Conversely, ISO 27001 is completely risk management-based and has risk management at its foundation whereas ISO 20000 encompasses much more
Why ISO 20000?
Organisations should ask themselves how they will derive value from ISO 20000. In Short, the ISO 20000 certification gives ITIL ‘teeth’. ITIL is not prescriptive, it is difficult to maintain momentum without adequate governance controls, however – ISO 20000 is. ITIL does not insist on continual service improvement – ISO 20000 does. In addition, ITIL does not insist on evidence to prove quality and progress – ISO 20000 does. ITIL is not being demanded by business – governance controls, auditability & agility are. This certification verifies an organisation’s ability to deliver ITSM within ITIL standards.
Ensuring ISO 20000 compliance provides peace of mind and shortens the journey to achieving other certifications, such as ISO 27001 compliance.
