Public cloud has been underestimated with respect to enterprise architect. Initially, cloud platforms like SaaS, PaaS, and IaaS are used by small organizations.
However, with changing cloud image, organizations of all sizes are adopting and deploying public cloud from SaaS, PaaS, and IaaS with their internal on-premise systems. The challenge is rising in figuring out the integration of those public cloud services with existing corporate systems.
In a coming couple of years, corporates are keeping an eye on shifting their key computing workloads to the public cloud platform in order to take maximum advantage of automated software management, elastic scalability, rapid project implementation, and pricing models (subscription-based). That way IT is serving as an outside service broker. Trends like these are making IT departments in formalizing enterprise architecture and enterprise governance to minimize risk factors.
System Integration On-Premise with Public Cloud SaaS
Enterprise architects must evaluate values delivered through public cloud SaaS platform being adhered to open standards. Point to point system integration covers following key parameters:
- Data Integration: A company’s architecture must understand data shifting process from their on-premise systems to public cloud SaaS applications. Understanding of tools and technology associated with SaaS offerings can lead to smooth data transferability.
- Business Process and Business Intelligence Integration: Business processes must be shortlisted by an organization that is best suitable for process automation. Also, an organization must learn to blend data between both on-premise and public cloud system.
- User Identity and Security Integration: The level of data security is dependent on how well a company integrates user identity and access control.
Public cloud offers design patterns and clear capabilities to enable an enterprise architect in implementing smooth integration across HCM, ERP, and CRM domains.
System Integration On-Premise with Public Cloud PaaS and IaaS
Enterprises are in favor of public cloud IaaS and PaaS offerings for a number of reasons as mentioned below:
- Smooth functionality of critical applications
- To improve the functionality of departmental applications
- To securely store and also archive company-wide data
- To store and archive data in an economical manner
- To modernize internal hardware infrastructure
- To achieve elastic scalability
Public cloud enables corporates in managing their identity from a single point. Public cloud serves as a center point for handling data residency. All integrated solutions offered by public cloud hugely benefit IT organizations in maintaining performance consistency from one service to another.
Keeping Long-Term Foresight
The new frontier that we are talking about must intersect both public and private cloud. Just going for public services is not going to fulfill enterprise requirements; those services must prove themselves by mitigating corporate risks along with the provision of seamless business processes. A well-planned architecture prevents corporates from having unexpected nightmares concerning point-to-point integration.
