"All our customers are looking at the cloud ecosystem as an important part of their overall product strategy. Some see it evolve as a multi-cloud / hybrid cloud strategy, while others are embracing all forms of cloud offerings like PaaS, IaaS and SaaS in their solutions," noted Suhas Joshi, Vice President - Technology, at Harbinger Group, in this exclusive Q&A with Cloud Expo Conference Chair Roger Strukhoff.
Cloud Computing Journal: It seems we're now in the era of hybrid cloud and multi-cloud. To what degree does this hold true for your customers?
Suhas Joshi: As large enterprises begin to embrace cloud computing, the multi-cloud and hybrid cloud era is a natural evolution. Privacy and security considerations in the past led to the emergence of a private cloud offering. The success of SaaS offerings (like salesforce) and their adoption in enterprises is taking us to a hybrid cloud and multi-cloud era. Social strategies of businesses are also influencing the business processes. As a result the need to integrate enterprise systems with external systems is growing, which makes the multi-cloud era a reality.
We, at Harbinger Systems, provide design and development services to Independent Software Vendors. With more than a decade's association with some of our customers, who service enterprises of varying sizes, we witnessed this evolution as their products addressed the changing needs of enterprises. Our customer's products have begun to play a role in this new era of cloud computing in terms of the provision of service APIs to be consumed by enterprise systems.
Cloud Computing Journal: What role do you see PaaS playing for your customers and to what degree is PaaS being integrated into IaaS?
Joshi: We have seen different perspectives on PaaS with our customers.
With providers combining ease of application development and deployment, the degree of integration of PaaS and IaaS is certainly growing. There are certain advantages too. But we have yet to see full use of this integrated offering.
This integration of PaaS and IaaS offerings from cloud vendors reminds me of the days when DBMS vendors first added development platforms and domain-specific solutions on top of their database infrastructure for ease of development of applications.
Cloud Computing Journal: How important are containers and microservices to your company and to your customers?
Joshi: While service-oriented architecture was an integral part of solutions built by Harbinger for our customers, most of the systems were classical multi-tier client/server systems with services at the presentation, business and data access layers. The RESTful services in these solutions served us well in evolving our customer's products to integrate with third-party systems as well as support the mobility strategy.
In the past few quarters, we have seen enterprise customers and a few ISV customers thinking seriously about microservices and using the containers hosting them.
As microservices force us to think about fine-grained distributed services to be the elements of service-oriented architecture, we have seen that customers with an architecture strategy based on distributed reusable components (deployed as microservices) are the ones who will use these technologies first.
Our experience in building solutions using SOA and the insights we got from working with distributed component models of the pre-web era gave us the right foundation to ensure the success of our customers as they adopt the distributed model with microservices and containers.
Cloud Computing Journal: To what degree does an entire cloud ecosystem play a role in your customer needs and visions?
Joshi: As mentioned earlier in the hybrid and multi-cloud question, all our customers are looking at the cloud ecosystem as an important part of their overall product strategy. Some see it evolve as a multi-cloud / hybrid cloud strategy, while others are embracing all forms of cloud offerings like PaaS, IaaS and SaaS in their solutions. The degree to which they will use a variety of options will also depend on the readiness of their customers to use cloud-based solutions and the new products they will integrate with in the future.

Containers & Microservices Expo To Be Colocated with Cloud Expo Silicon Valley, November 3-5, 2015 at the Santa Clara Convention Center, CA
Containers and microservices have become topics of intense interest throughout the cloud developer and enterprise IT communities.
Microservices focuses on the business and technology of the software architecture design pattern, in which complex applications are composed of small, independent processes communicating with each other using language-agnostic APIs.
Containers are not being considered for the first time by the cloud community, but a current era of re-consideration has pushed them to the top of the cloud agenda.
Rather than just stuff an OS into a container, for example, developers and deployers should consider a spectrum of microservices and what they can do.
