In the wake of the unprecedented challenges of 2020, IT leaders are urged to refine their strategies for 2021 by focusing on several key areas to enhance their technological infrastructure. The emphasis is on managing cloud costs by controlling cloud spending, with reports indicating that 30% of such spending is wasted. Security measures should be prioritized given the frequency of data breaches, necessitating a deeper examination of both data at rest and in motion. The importance of embracing multicloud strategies is highlighted to avoid dependency on a single vendor and ensure global service availability. Simplifying Kubernetes configurations, advancing analytics towards real-time capabilities, addressing database sprawl, and preparing for edge computing are all crucial steps in modernizing IT systems. The overarching goal is to build resilient, efficient, and cost-effective systems that can adapt to the dynamic nature of modern business environments.
