IDC research confirms that hybrid IT is the predominant posture of At A Glance for IDC Reportlarge enterprises worldwide. In an IDC Cloud Pulse Survey conducted in June 2020, enterprise respondents indicated that about 50% of their applications would still be running in on-premises datacenters in two years.

In this environment, modern networks are critical. They not only must contribute to an organization's digital transformation (DX) strategy but also must proactively support an organization's increasingly valuable applications. Failure to recognize the salience of modern networks —and the significant challenges presented by hybrid architectures —can result in infrastructure and operational issues that compromise business outcomes. To mitigate these risks and simplify hybrid networking for architects and NetOps teams, organizations require modern network architectures, advanced network tooling, and an intelligently automated operational approach that includes well-defined and continuous network validation from Day 0 through Day 2/N.

At Day 0, the ability to run simulated what-if scenarios in a staged environment ensures that everything will work according to plan when the network goes live. Once Day 0 validation confirms that it will, operators can push and commit changes that are then automatically applied in a live environment. Further validation also verifies that the network is behaving as intended. From there, Day 2 automation that employs streaming telemetry and advanced analytics provides actionable visibility to facilitate faster and more effective troubleshooting and remediation.

Further, closed-loop insights in Day N scenarios enable operators to manage change and further optimize the network. From a more proactive network automation posture, operators can anticipate, predict, and preclude potential issues while automating routine tasks.

Traditional network architectures are too rigid, and manual network operations are too inflexible to deliver such functionality and benefits. Consequently, overburdened NetOps teams are unable to keep pace with the changes that are required to support applications and reach business outcomes. Most of their time is spent triaging problems (i.e., fighting fires) rather than proactively innovating to make the network a meaningful enabler of business outcomes and DX success.
