Where Do Core Applications Belong? IT leaders are caught in a dilemma when it comes to deployment of core enterprise applications. One side is continuing the expensive and time-intensive effort to maintain and adapt legacy applications, even though it seems they increasingly hinder business activity rather than help it. – Enterprise Applications
The other side is adopting new applications that run in the cloud—an environment that offers promising potential, but is also unfamiliar and may be perceived as risky. Until recently, enterprises used the cloud only for new applications or for those specific to an individual department or business unit. Now, with the growing strength of cloud application offerings, enterprises are starting to consider replacing the core applications traditionally hosted in on-premises systems and put those in the cloud, too.
The success of any move to the cloud depends in part on the architecture that underlies the cloud service or application. When looking at potential cloud solutions for core systems, it is important to understand the different cloud architectures and how they impact application capabilities and performance—and the difference that makes for migration from current systems.
There are many reasons why IT organizations have been cautious in the past about making the switch to cloud for
core applications. Yet the benefits of today’s cloud offerings mitigate those concerns.
Initial resistance to cloud adoption often comes from the idea of abandoning large investments in existing systems. Many core enterprise applications encompass years of expense, staffing, data center infrastructure, user training, and a CIO’s internal political capital.
This level of investment can make it hard to embrace a complete replacement of current systems, as long as their
performance and flexibility are perceived as adequate and users are willing to tolerate them. However, the upgrade
process for on-premises systems is so costly and complex that organizations may also be slow to adopt newer versions.
This factor makes the cloud attractive because system maintenance and updates are performed by the vendor. (SaaS) offering, this balance is managed by the vendor and delivered through contractual service level agreements (SLAs). In turn, IT can focus resources on delivering the services required by the business.
Another unsubstantiated fear about replacing applications is that they will be less secure when running in the cloud than on in-house servers. In fact, the security capabilities of a cloud provider can be stronger than what is feasible or affordable for an IT organization to maintain itself. But it is important to understand a provider’s security capabilities, especially the model used by the application for data storage and access.
Any application will need to be customized to fit the specific needs of the business. But there are important differences in how vendors support those customizations, and for maintaining that support in new versions of the cloud application. Look for a vendor that sustains customizations in new software releases. Contact Musato Technologies today to learn more about our innovative ICT services.
