Navigating Cloud Migration: Cost Control, Security, and Strategic Cloud Selection
Accomplished cloud migration hinges on careful planning and ongoing management, focusing on both cost and security. Common pitfalls include a lack of understanding regarding the true operational costs of cloud systems and insufficient monitoring and control mechanisms.
Regarding security, a foundational step is disabling unnecessary internet access during the initial cloud setup. Establishing secure communication channels between systems, and between systems and their access points, is also critical.Robust monitoring systems are essential for detecting anomalies and triggering timely responses from the appropriate teams.
Cost management centers around the workloads themselves. Key factors include the nature of the applications being run, the hardware resources allocated, and the specific features utilized. Cloud providers offer tiered storage options with varying price points, requiring careful consideration to optimize spending.
Pega’s own migrations offer valuable insights. In 2020, the company successfully migrated its ERP implementation from a colocated data center to Google Cloud in 13 weeks, encompassing the planning and migration of over 40 development, testing, and production environments.This was achieved through thorough initial testing, including multiple mock runs to ensure environment security and proper sizing to avoid unnecessary costs. Further savings were realized by reserving capacity onc performance profiles were understood.
A subsequent migration to AWS enabled Pega to leverage elastic capacity and readily access cloud-based AI capabilities. This facilitated faster integration of new functionality into applications, bypassing traditional licensing and procurement processes.
However,a broader migration strategy requires recognizing the strengths of different cloud providers.organizations utilizing multiple clouds – AWS, Google, and Azure – must be aware of data egress charges and carefully consider system placement and communication patterns. The location of systems, whether consolidated within a single cloud or distributed across multiple, considerably impacts overall costs.
