Cloud IT- Modern enterprises are migrating applications to the cloud, replacing legacy technologies with new cloud-based architectures that offer numerous advantages, including lower costs, increased efficiency, and the ability to scale workloads on demand. This flight has turbulence, however. A recent report by Gartner analysts Padraig Byrne and Sanjit Ganguli shows how cloud adoption presents significant challenges, including:
- IT operations teams no longer have the same access to the infrastructure and networks that support their services, thus creating visibility gaps in monitoring.
- An enterprise’s cloud migration effort is often spearheaded from outside the infrastructure and operations (I&O) team, which—though it has limited say on the matter —is still held responsible for service availability.
- IT ops teams often lack the skills to monitor cloud-based services and struggle to find experts who can.
In addition, with the move to microservices, containers, and serverless technologies, workloads running in the cloud have now become much more dynamic and ephemeral. All of this change and uncertainty leads to a startling prediction: By 2021, less than 15% of organizations will implement holistic monitoring, putting $255 billion of investments in cloud-based solutions at risk, Gartner notes.
So, how can IT organizations maintain a high level of service quality when running applications in the cloud and still realize the benefits that they expect? Byrne and Ganguli offer three key steps that IT ops leaders and managers can take to lessen visibility gaps and sustain service quality.
1) Inventory the cloud types in your environment. While running applications in the cloud outsources much of the complexity of IT infrastructure, it also introduces new visibility gaps in monitoring.
The type of cloud architecture—including private cloud, infrastructure as a service (IaaS), platform as a service (PaaS), and software as a service (SaaS)—has a big impact on your ability to monitor it, the Gartner analysts note. For example, private cloud offers the most control because IT operations owns the entire stack. In this environment, IT ops generally will use traditional monitoring techniques.
Visibility gaps present a far greater problem with IaaS, PaaS and Saas cloud architectures. With IaaS, for instance, everything below the OS is now beyond the view of IT operations, which can’t utilize traditional monitoring techniques that rely on access to the hypervisor or virtual switch.
