AppFirst has launched its SaaS-based application performance monitoring service and said that it has raised an undisclosed amount of capital from FirstMark Capital and First Round Capital. The company disclosed $1M in funding in a regulatory filing.

In a move to enter the burgeoning SaaS-based IT management market, Citrix Online announced its acquisition of Menlo Park, Calif.-based Paglo Labs. The acquisition is an integrated web-based platform for monitoring, controlling and supporting IT infrastructure.

Dubbed GoToManage, the new service lets Citrix Online tap into the growing demand for software-as-a-service (Saas)-based IT management, a market Forrester Research predicts will reach $4 billion in 2013. Citrix Online is positioning the latest addition to its online services portfolio as an affordable alternative to premise-based software.
