Digital Transformation – Take Advantage of Application Delivery in Your Journey

The adoption of new technologies is accelerating business transformation. In its essence, the digital transformation of businesses uses technologies to drive significant improvement in process effectiveness.

Cloud computing is one of the core technologies for Digital Transformation

Increasing maturity of cloud-based infrastructure enables organizations to deploy business-critical applications in public and private cloud. According to a new forecast from the International Data Corporation (IDC) Worldwide Quarterly Cloud IT Infrastructure Tracker, total spending on IT infrastructure for deployment in cloud environments is expected to total $46.5 billion in 2017 with year-over-year growth of 20.9%. Public cloud data centers will account for the majority of this spending, 65.3%, growing at the fastest annual rate of 26.2%.

Many enterprises are in the midst of this transition to the cloud, whether moving to a public cloud, building their own private cloud or managing a hybrid deployment. In this fluid environment, where new services are being frequently added and old ones updated, the new paradigm requires support for needs across multiple environments and across many constituencies – an IT administrator, an application developer, DevOps and tenants.

Nobody Said It Was Easy!

However, the process of migration of applications to the cloud is not easy. The flexibility and cost benefit that drives the shift to the cloud also presents many challenges – security, business continuity, and application availability, latency reduction, issues with visibility, SLA guarantees and isolation of resources.  Some other aspects that require some thought – licensing, lock-in with a cloud service provider, architecture to address hybrid deployment, shadow IT, automation, user access, user privacy, and compliance needs.

One of the main challenges for enterprises moving to a cloud infrastructure is how to guarantee consistent quality of experience to consumers across multiple applications, many of which are business critical developed using legacy technologies and still hosted on-premise.

Along with the quality of experience, organizations need to look at the security policies. Sometimes policies require integration with a cloud service provider’s infrastructure or require new capabilities to complement on-premises architecture while addressing denial of service, application security and compliance for new attack surface exposed by applications in the cloud.

Convenience and productivity improvements are often the initial drivers for adopting IT services in the cloud. One way to address security and availability concerns for the enterprise embarking on the cloud journey is to ensure that the security and availability are also included as part of IT self-service, orchestration and automation systems, without requiring additional effort from those driving adoptions of cloud-based IT applications.

The World of Application Delivery Has Changed to Adapt!

Application delivery and load balancing technologies have been the strategic components providing availability, optimization, security and latency reduction for applications. In order to enable seamless migration of business-critical applications to the cloud, the same load balancing and application delivery infrastructure has to evolve to address the needs of continuous delivery/integration, hybrid and multi-cloud deployments.

This is the last part of the blog series exploring the various alternatives for protection against DDoS attacks, and how to choose the optimal solution for you. The first part of this series covered premise-based hardware solutions, the second part discussed on-demand cloud solutions, and the third part covered always-on cloud solutions. This final piece will explore hybrid DDoS solutions, which combine both hardware and cloud-based components.

Hybrid Cloud – It is Not the Migration that Hurts

November 15, 2016 — by Frank Yue — 0

The last time I moved was 10 years ago. At the time, I told myself that this is the last time I am moving. The packing and relocation of my belongings was not too much trouble. The main problem is trying to get everything sorted out and put into their proper place in the new home.

When businesses migrate applications to the cloud, the process is similar. They are very familiar with the applications and their data. The problem is that they need to understand how the applications will behave in the new environment. Where does the data reside and how do the clients access the application’s new home?

Hybrid Cloud is Not the Goal – A Case for Full Virtualization

November 10, 2016 — by Frank Yue — 0

In the world of cloud and virtualization, the buzz word of the day is ‘hybrid’. Everyone wants a hybrid cloud environment because they want to get the benefits of the cloud without relinquishing control of their applications and infrastructure. IT departments want the cost savings along with the agility and elasticity that cloud technologies bring, but they are not comfortable with the complete migration of their applications and data to a managed infrastructure.

Today, there are two primary use cases where companies are putting applications and data into the cloud. The difference between the two cases depends on whether it is an existing application or a new one that is being deployed. In the former, there is legacy infrastructure and support that has to be accounted for while the latter provides a greenfield opportunity to create an ideal infrastructure from the start.

The cybersecurity industry keeps us all on our toes trying to follow up with solutions and breakthrough technologies – not only in advanced security capabilities, but also with state of the art methods of management and integration with other network security elements.

You want your security elements to play together in a well synchronized manner. You wouldn’t want to have to intervene to frequently make manual adjustments, would you?

Hybrid Cloud is Not Genetically Modified, But You Can Still Benefit

December 8, 2015 — by Frank Yue — 0

When I hear IT people use the term hybrid, I recall my background and education in biology.  In the biology community, hybrid usually refers to the result from a combination of two different species or subspecies.  For example, a zonkey is a cross between a zebra and a donkey.  More recently, hybrids have also been associated with the controversial practice of genetically modified crops where genes from completely different organisms are spliced into a plant to provide an otherwise unavailable benefit.  Some strains of corn have had a gene added to improve their resistance to popular herbicides.

How Application Delivery Can Simplify Enterprise Challenges

June 24, 2015 — by Prakash Sinha — 0

In enterprise environments it is common for an application to be hosted by a pool of servers, either physical or virtual.  Over time these applications also go through a lifecycle that consists of security patches, maintenance, upgrades to update capabilities, and changes to keep up with trends such as virtualization, consolidation and deployment in a hybrid cloud environment.  For scalability, additional servers may also be deployed.
