Solution brief eNlight Cloud B2B Enterprises & e-commerce Cloud Computing

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 of benefits cloud computing offers − from lower capital and operating costs to greater scalability, accessibility and manageability, digital transformation is no 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 cloud service-based market will grow by 18 percent by 20172 with the shift from traditional IT set-ups to cloud-based infrastructures estimated to affect more than 1 trillion in IT spending by 2020.

“ As part of our commitment to accelerate digital transformation among enterprises, Intel helped ESDS build their cloud Business Challenge: B2B cloud-migration is a complex infrastructure in line with process with operational and security risks their scalability, security and Although cloud-migration appears to be the way forward for most enterprises, the journey to the clouds isn’t always linear. First, enterprises will need to replicate availability requirements. 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 for newer platforms. Next, they will need to establish their migration strategy out performance of the new of the five migration strategies available: full migration, iterative migration, limited Intel® Xeon® Scalable migration, vertical migration and horizontal migration.

Full migration entails a “lift and shift” of an existing IT infrastructure to a new Processors, resource infrastructure while the iterative migration and limited migration employs provisioning across diverse a component-by-component migration strategy for business applications comprising multiple modules, and in the case of the latter – a migration strategy workloads will now be that mandates the moving and modification of specific components to optimize faster and smoother than interoperability with existing applications. ever before.”

Since legacy systems are tightly-coupled architecture with interdependent components that handle business-critical legacy file format and applications, they cannot be simply lifted and shifted. Similarly, iterative and limited migration strategies are just as unfeasible due to the extended downtime involved for the former, and the technical risks the latter brings. That leaves us with the vertical and horizontal migration strategies. Of the two, the horizontal migration strategy is most commonly employed by B2C and ecommerce businesses as the majority of their apps and databases are typically designed to scale outwards.

However, this approach is not ideal for B2B enterprises since most still operate legacy systems, whose tightly coupled DNA contrasts with the loosely coupled framework of horizontal architectures. In some cases, migrating legacy applications to a horizontal architecture may result in extended downtime or operational failure. To avoid these risks, a number of B2B enterprises end up making do with their existing dedicated servers.

Another alternative would be a vertical architecture. Unlike horizontal architectures, which scale by increasing the number of servers to cope with higher workloads, vertical architectures scale by adding more CPUs and RAM to an existing server. That said, vertical architectures can be scaled with no change to the code and are generally easier to manage as data is traditionally stored in one robust server unlike its horizontal counterparts, which distributes data across a fleet of smaller-scale, virtual machines. However, there is a catch − vertical architectures come with scalability limitations and are only scalable to the size of their server.

While there are numerous cloud service providers, most only offer a horizontal architecture. To address the gap in cloud service offerings catered to B2B enterprises, ESDS brought together a team of highly experienced engineers to develop a highly agile and scalable cloud-based architecture with auto-scaling technology. For the system to be successful, any modifications should be seamless for the end-user. On top of that, this system should also be capable of orchestrating resource provisioning in real time to respond to any sudden increase or decrease in traffic or data load.

Optimizing hardware performance with Intel inside After evaluating an array of scaling methodologies and their implications, it became clear to ESDS that the most ideal solution would be an integrated cloud infrastructure with horizontal and vertical scaling functionality, built-in data security and reduced latency.

Designed with a comprehensive array of enterpriselevel features that delivers powerful yet energy-efficient performance, the all-new Intel Skylake-SP architecture not only presented ESDS engineers with a scalable platform to efficiently and cost-effectively develop their next-generation cloud-computing solution but also offered seamless integration with their existing platform and backwards compatibility with older versions of Intel processors, ensuring future enhancements can be implemented with minimal downtime and reconfiguration.

By leveraging on Intel® Xeon® Scalable Processors, ESDS was able to achieve best-in-class performance, security, agility and efficiency on eNlight Cloud - the first-of-its-kind, auto-

scalable, managed cloud solution with vertical and horizontal scaling functionality.

On top of that, these processors also helped improve data security, resource utilization and system uptime on eNlight Cloud, while retaining workload isolation. A virtual machine density test performed by ESDS on the deployed Intel® Xeon® Platinum 8170 Processors demonstrated that the key to successfully increasing virtual machine consolidation is largely dependent on the core count of the server and not just the virtualization technology used.

To prevent bottlenecks in resource provisioning, typically caused by depleted memory resources (RAM), proper memory resource management should be implemented to ensure a higher number of mission-critical virtual machines can be deployed on demand.

Through the deployment of the new Intel® Xeon® Platinum 8170 Processors, which feature 26 cores and a 2.1 GHz clock speed, eNlight Cloud was able to achieve a huge boost with the overall performance of eNlight Cloud, and generate up to 176 virtual machines per server3.

With these dense 26-core processors, multitasking will be faster than ever before as more cores can be deployed to execute mission-critical tasks. So, in the event one of two cores are engaged, other available cores within the processor can spring into action to execute the tasks on-hand instead of stalling the job.

A faster and safer B2B cloud migration strategy With eNlight Cloud, B2B enterprises can accelerate their journey to the clouds without incurring downtime or operational risks as eNlight Cloud is built with a live migration feature that allow servers to be migrated without downtime. In addition to that, eNlight Cloud can also efficiently and securely replicate the original execution requirements of enterprises’ legacy applications without disrupting operations or requiring any modification or redesign of the application programming interface (API).

From a cost perspective, eNlight Cloud delivers massive savings through the complete eradication of capital investments and substantially lowered operating costs. Unlike physical servers, which require hefty upfront investments, eNlight Cloud requires no sunken costs since its servers are hosted on the cloud. In addition to that, it also operates on a metered, pay-per-consume billing model that charges enterprises only for utilized resources – so, enterprises will no longer have to incur unnecessary costs from over-allocation of resources.

On the operations side, eNlight Cloud offers greater agility, scalability and accessibility as it comes with an intelligent auto-scaling feature that can elastically scale up RAM, CPU and bandwidth during peak periods to cope with increase in workloads. Best of all, operations remain unaffected during the scaling process as eNlight Cloud can perform a live server upgrade. Managing servers will be significantly easier with eNlight Cloud as it provides a host of on-demand services that end-users can tap on to automatically deploy, manage or repair virtual machines, from wherever they are through a web-based console. Even without access to a computer, users can enjoy unparalleled access their cloud via the dedicated eNlight Cloud mobile app.
