Analysts and industry watchers agree that the next frontier for SaaS is setting distribution channels designed specifically for the cloud and providing mechanisms for managing multiple SaaS offerings from a single control point. These SaaS deployment advancements will likely come from a variety of sources: established SaaS vendors, start-ups providing SaaS channel enabling software, and cloud service brokerage houses. Here are 10 companies leading the charge.\n10 SaaS delivery companies to watch\nAppDirect\nCompany: AppDirect\nHeadquarters: San Francisco\nWhy we\u2019re watching: Think of AppDirect Ecosystem as a Marketplace as a Service (MaaS) offering which provides the platform for Cloud Service Brokerages (CSB) to build bundled SaaS offerings for regional, business process focused or vertical markets. Among the SaaS applications aggregated into this platform are GoogleApps, Office365 and TribeHR. Some of the CSBs that have bought into AppDirect\u2019s platform are Bell Canada and Deutsche Telekom.\nConcur\nCompany: Concur\nHeadquarters: Redmond, Wash.\nWhy we\u2019re watching: Concur is a leading provider of integrated travel and expense SaaS. It\u2019s got both 15,000 existing users and a grand plan to get many more thousands thanks to a tight partnership with Salesforce.com. Dubbed ConcurForce, the partnership allows for data integration between the two SaaS offerings so that companies can understand how expenses are directly correlated with reeling in new sales leads. Since expenses touch everything, it will be interesting to see with which other software builders Concur will align its data.\nIngram Micro\nCompany: Ingram Micro\nHeadquarters: Santa Ana, Calif.\nWhy we\u2019re watching: According to the recently published Cloud & Technology Transformation Alliance\u2019s (CTTA) State of the Channel Cloud Report, Ingram Micro has the mindshare advantage among traditional software distributors when it comes to convincing software makers they\u2019ve got a solid strategy for distributing SaaS going forward. That said, the report also states that this segment of the SaaS delivery channel has been a bit stymied by an inability to find cloud-experienced sales and technical staff.\nJamcracker\nCompany: Jamcracker\nHeadquarters: Santa Clara, Calif.\nWhy we\u2019re watching: Jamcracker has a long history -- 13-years, in fact \u2013 in aggregating and distributing on-demand services through a global ecosystem of service providers, resellers, system integrators, and ISVs, called the Jamcracker Services Delivery Network (JSDN). Services available through the JSDN include messaging, collaboration, security, online data backup, wireless, and business productivity solutions from Microsoft, Cisco, McAfee, Blackberry, IBM, Google, and dozens of other cloud providers.\nOspero\nCompany: Ospero\nHeadquarters: London, England\nWhy we\u2019re watching: Ospero is an Infrastructure as a Service (IaaS) vendor that is looking to use its underlying federated VMware cloud running on a VCE VBlock hardware to build a better SaaS delivery channel into the enterprise across Europe. They call the prospect distribution-as-a-service (DaaS) and the goal is to help SaaS vendors rollout global instances without the worry of legal data residency compliance, latency issues and privacy headaches.\nNetSuite\nCompany: NetSuite\nHeadquarters: San Mateo, Calif.\nWhy we\u2019re watching: NetSuite is an undisputed leader in the Accounting and ERP segments of the SaaS market. It\u2019s followed the same Salesforce.com model of building its SuiteApps.com applications marketplace around its core offering. But the company has also forged several key partnerships under its SuiteCloud program \u2013 including GoogleApps, SalesForce.com, SAP and Oracle -- to provide complete integration between their on-premise and cloud applications.\nParallels\nCompany: Parallels\nHeadquarters: Seattle, Wash.\nWhy we\u2019re watching: Parallels has a long history in and around virtualization and cloud computing. It\u2019s got significant experience as the provider of infrastructure, application and end user cloud enablement software and it takes all three levels into account as it\u2019s developed its SaaS marketplace software. Among its customers are Cincinnati Bell, Insight, Apptix and Sprint.\nSalesforce\nCompany: Salesforce.com \nHeadquarters: San Francisco\nWhy we\u2019re watching: This SaaS giant cannot be ignored due to its track record for success in the cloud. With its huge 200,000 customer base, it\u2019s no wonder that its AppExchange marketplace for complementary products has ballooned to include over 1,400 applications. It will be interesting to see how SalesForce.com opens up deeper integration between the products to help drive SaaS sales deeper into corporate IT.\nStanding Cloud\nCompany: Standing Cloud\nHeadquarters: Boulder, Colo.\nWhy we\u2019re watching: Standing Cloud provides cloud application management services built on a Platform-as-as-Service (PaaS) offering that supports multiple programming languages, including Rails, PHP, Java and Python, and a wide range of cloud service providers and orchestration software systems. It also offers a standard application catalog that includes 100 open-source and commercial applications. The combination is meant to offer a seamless application layer for cloud service providers that, in turn, will make application deployment and management fast, simple and hassle-free for their customers.\nWorkDay\nCompany: WorkDay\nHeadquarters: Pleasanton, Calif.\nWhy we\u2019re watching: WorkDay was founded in 2005 by co-CEOs Aneel Bhusri and Dave Duffield and currently offers cloud-based human capital management SaaS that can analyze workforce expenses and manage the process of paying staff. And it\u2019s making good money at it too. We\u2019re watching this firm closely because it\u2019s staring down on-premise competitors Oracle and SAP. This is turning into a battle of might versus agility and should result in some interesting twists on how to deliver SaaS smarter, quicker, cheaper.
