Solution brief eNlight Cloud B2B Enterprises & e-commerce A highly versatile, agile and elastic cloud solution that automatically provisions resources to meet business-critical demands

Intel and ESDS join forces to help B2B enterprises accelerate their cloud migration journey Dedicated servers are no longer sustainable as they age due to their lack of scalability, agility and high operating costs. Unlike cloud servers, which allow resources to be dynamically provisioned in tandem with real-time demands, on premise servers rely on pre-allocated resources. Given the challenges involved with resource planning, IT managers inevitably end up over- or under-allocating computing resources such as bandwidth, CPU and RAM. To manage data growth more efficiently, many enterprises are turning to cloud computing. 38% of enterprise IT organizations have already adopted cloud computing, a figure projected to increase to 45% by 2019.1 Considering the myriad “As part of our commitment of benefits cloud computing offers − from lower capital and operating costs to greater scalability, accessibility and manageability, digital transformation is no to accelerate digital longer a question of why but when. Findings from Gartner, the leading global IT research firm substantiates this. A report by Gartner estimates that the public transformation among cloud service-based market will grow by 18 percent by 20172 with the shift from enterprises, Intel helped traditional IT set-ups to cloud-based infrastructures estimated to affect more than 1 trillion in IT spending by 2020. ESDS build their cloud infrastructure in line with Business Challenge: B2B cloud-migration is a complex process with operational and security risks their scalability, security and Although cloud-migration appears to be the way forward for most enterprises, the availability requirements. journey to the clouds isn’t always linear. First, enterprises will need to replicate their existing mission-critical legacy apps and systems to prepare for the move to With the best-in-class the cloud. This process essentially involves adapting existing system components performance of the new for newer platforms. Next, they will need to establish their migration strategy out of the five migration strategies available: full migration, iterative migration, limited Intel® Xeon® Scalable migration, vertical migration and horizontal migration. Processors, resource Full migration entails a “lift and shift” of an existing IT infrastructure to a new infrastructure while the iterative migration and limited migration employs provisioning across diverse a component-by-component migration strategy for business applications workloads will now be comprising multiple modules, and in the case of the latter – a migration strategy that mandates the moving and modification of specific components to optimize faster and smoother than interoperability with existing applications. ever before.”

Similarly, iterative and limited migration security, resource utilization and system uptime on eNlight strategies are just as unfeasible due to the extended Cloud, while retaining workload isolation. A virtual machine downtime involved for the former, and the technical risks density test performed by ESDS on the deployed Intel® Xeon® the latter brings. That leaves us with the vertical and Platinum 8170 Processors demonstrated that the key to horizontal migration strategies. Of the two, the horizontal successfully increasing virtual machine consolidation is largely migration strategy is most commonly employed by B2C and dependent on the core count of the server and not just the ecommerce businesses as the majority of their apps and virtualization technology used. databases are typically designed to scale outwards. To prevent bottlenecks in resource provisioning, typically However, this approach is not ideal for B2B enterprises caused by depleted memory resources (RAM), proper memory since most still operate legacy systems, whose tightly resource management should be implemented to ensure a coupled DNA contrasts with the loosely coupled framework higher number of mission-critical virtual machines can be of horizontal architectures. In some cases, migrating legacy deployed on demand. applications to a horizontal architecture may result in extended downtime or operational failure. To avoid these Through the deployment of the new Intel® Xeon® Platinum risks, a number of B2B enterprises end up making do with 8170 Processors, which feature 26 cores and a 2.1 GHz clock their existing dedicated servers. speed, eNlight Cloud was able to achieve a huge boost with the overall performance of eNlight Cloud, and generate up to 176 Another alternative would be a vertical architecture. Unlike virtual machines per server3. horizontal architectures, which scale by increasing the number of servers to cope with higher workloads, vertical With these dense 26-core processors, multitasking will be architectures scale by adding more CPUs and RAM to an faster than ever before as more cores can be deployed to existing server. That said, vertical architectures can be execute mission-critical tasks. So, in the event one of two scaled with no change to the code and are generally easier cores are engaged, other available cores within the processor to manage as data is traditionally stored in one robust server can spring into action to execute the tasks on-hand instead of unlike its horizontal counterparts, which distributes data stalling the job. across a fleet of smaller-scale, virtual machines. However, there is a catch − vertical architectures come with scalability A faster and safer B2B cloud migration limitations and are only scalable to the size of their server. strategy While there are numerous cloud service providers, most only With eNlight Cloud, B2B enterprises can accelerate their offer a horizontal architecture.
