Cloud computing management software provider RightScale has scored $13 million in second round venture funding. Index Ventures led the round and was joined by returning investor Benchmark Capital, which led a $4.5 million round in April. Index Ventures partner Danny Rimer has also joined the RightScale’s board of directors. The funding is another proof point that venture firms are still investing in cloud computing plays despite the downturn. RightScale, as well as its competitor Elastra, which raised money in August, are fueled up for the downturn. Let’s see if they can get anywhere, especially as the larger providers such as IBM start moving in with their own cloud management and provisioning services.
