The text discusses the limitations of PostgreSQL in financial services, emphasizing its challenges with horizontal scaling, distributed architecture, and managing downtime. PostgreSQL, despite its stability and ACID compliance, struggles with scaling horizontally, which is crucial for processing numerous transactions per second, and often requires manual sharding that is costly and risky. The distributed architecture of PostgreSQL also presents issues, as it relies on a single write node, creating bottlenecks in distributed transactions. Furthermore, PostgreSQL is not well-suited to handle unplanned downtime caused by unforeseen events, and planned downtime for updates can be costly. The article highlights why Stash migrated from PostgreSQL to CockroachDB, a fully distributed SQL database that offers better scalability, resilience, and lower latency. CockroachDB's ability to scale out both reads and writes across regions made it an attractive option for Stash, ensuring high availability and multi-region, multi-cloud capabilities.

This development allows healthcare companies and SaaS organizations that cater to the healthcare industry to leverage the operational efficiencies of CockroachDB Dedicated while ensuring data security. The HIPAA-ready feature is part of the dedicated advanced plan, complementing existing certifications like PCI-DSS and SOC 2 Type 2, and Cockroach Labs also offers to sign a Business Associate Agreement (BAA) with interested customers.

The article by Charlie Custer explores the distinctions between multicloud, hybrid cloud, intercloud, and single-workload multicloud deployments, emphasizing the nuances and misconceptions surrounding these terms. Multicloud refers to the use of multiple public cloud services by a company, while hybrid cloud involves a combination of public clouds and on-premises infrastructure. Intercloud is a more specific type of multicloud where a single application runs across multiple clouds, and single-workload multicloud describes a single application service running across multiple clouds. The discussion includes the concept of cloud agnosticism, where a service can run on any major cloud platform. Key considerations for choosing the appropriate cloud deployment include risk mitigation, negotiation leverage, customer demands, regulatory compliance, existing infrastructure, technical complexity, talent acquisition, cost implications, tooling requirements, and the decision between lifting and shifting existing applications versus building new ones for multicloud. The article suggests that the decision to adopt a multicloud strategy should be based on a careful evaluation of these factors in the context of a company's specific needs and objectives.

The blog post by Dan Sheldon and Mike Bookham outlines the process of managing CockroachDB Dedicated using Terraform, a popular infrastructure-as-code tool, to prevent configuration drift and ensure optimal performance for applications at scale. The authors explain how to integrate CockroachDB with other software stack elements and deploy the complete infrastructure using pipeline tools. New features of the CockroachDB Terraform provider include retrieving database connection strings and certificates, using customer-managed encryption keys (CMEK), configuring maintenance windows, and integrating with Datadog for metrics visualization. The blog provides a detailed step-by-step guide for deploying a CockroachDB cluster on Cockroach Cloud, emphasizing the importance of managing infrastructure changes through Terraform rather than directly in the UI. The article highlights the continuous improvement of the CockroachDB Terraform provider, which is increasingly aligning with Cockroach Cloud's UI features, offering users enhanced capabilities for integrating and managing their database infrastructure.
