Migration & Modernization

Many organizations run business-critical workloads on VMware, and most know that a single outage can disrupt operations, impact customers, and put revenue and reputation at risk. Disaster recovery (DR) is the solution: a secondary environment ready to take over when the primary site goes down. But building one has traditionally meant heavy upfront investment, long […]

The Modernization Challenge Mainframe modernization projects often stall for the same reason; teams cannot capture what the legacy application does with enough precision to rebuild it confidently. The business logic running these applications is sound, it has processed millions of transactions daily for decades. But the applications themselves were written for a different era. They […]

Introduction Amazon Elastic VMware Service (Amazon EVS) now supports NSX Federation, giving you a powerful new option for enterprise-scale networking, disaster recovery, and multi-site networking when running VMware workloads on AWS. NSX Federation is a VMware networking capability that connects multiple NSX environments under a single Global Manager control plane. It extends overlay networking, security […]

As organizations migrate to AWS at scale, connecting migrated instances to their new storage is a common bottleneck. When workloads move from on-premises NFS servers to Amazon FSx for NetApp ONTAP, teams often mount file systems by hand, minutes per instance that add up to weeks across hundreds or thousands of servers. This solution combines […]

Every domain in a large-scale migration has tools. The network still has people: a handful of them, overbooked, carrying decades of accumulated decisions in their heads. That has just changed. It starts with the network When approaching a large-scale migration to the cloud, nothing moves until the network is ready. Not the database. Not the application. Not […]

Introduction In this blog post, we cover the post-cutover phase of an Oracle-to-PostgreSQL migration on Amazon Web Services (AWS), demonstrating how to transform a functional PostgreSQL system into an operationally excellent one. We walk through immediate validation, comprehensive observability, systematic performance optimization, disaster recovery validation, Oracle decommissioning, and the operational excellence foundation, including the continuous […]

Introduction In this blog post, we outline the target architectures and wave-based strategies needed to build functional PostgreSQL environments on Amazon Web Services (AWS), using Zulon City Insurance (ZCINS), a fictional carrier managing 42 Oracle databases, as a model for a successful transition. Once you have assessed your Oracle estate, as laid out in part […]

Introduction In this blog post, we explore the assessment phase of migrating Oracle databases to PostgreSQL on Amazon Web Services (AWS), the critical step that transforms your discovery inventory into an actionable migration strategy. After completing discovery of your Oracle estate in Part 1, you face the critical question: what will it take to migrate […]

Introduction In this blog post, we explore the discovery phase of migrating Oracle databases to PostgreSQL on Amazon Web Services (AWS), the foundational step that determines the success of every migration that follows. This is the first installment of a four-part series covering the Oracle-to-PostgreSQL migration journey, from initial discovery through post-migration optimization. Evolving licensing […]

Organizations running ASP.NET applications face a common dilemma: adding AI capabilities typically means significant refactoring or building entirely new systems. Your existing REST APIs contain years of valuable business logic, but there’s no straightforward path to make them AI-accessible without a rewrite. What if you could keep your code and add intelligence on top? In […]
