How to configure SQL Server High Availability with Always-On Availability Groups

Implemented network segmentation. Moved databases to private subnets (Azure: private subnets within a Virtual Network). No internet access. Problem: Primary database: private subnet Replica database: different private subnet Replication uses SSL SSL certificate validation needs external CA Private subnet can’t reach CA servers Certificate validation failed Replication stopped Temporary fix: Disabled SSL verification (bad idea) Replication worked Proper fix: Created Private Endpoint for Azure Key Vault Used Azure Key Vault Managed Private CA (or an internal PKI integrated via Azure AD / Key Vault) Issued internal certificates Configured trust chain Re-enabled SSL with internal CA Lessons learned: Network isolation breaks certificate validation Need internal PKI or Private Endpoints You can’t just “turn off internet access” Plan for certificate lifecycle management Extra finding: Database backup to Azure Blob Storage also broke Added Private Endpoint for the Storage Account Backups now run faster and avoid public internet Also reduced egress costs The insight: Security hardening often breaks existing functionality. Test thoroughly. Have rollback plans. Understand your dependencies. (The same concept applies in AWS using PrivateLink, ACM Private CA, and S3 VPC Endpoints.) #Azure #CloudSecurity #AWS #NetworkSecurity #AzureNetworking #PrivateEndpoint #AzureKeyVault #CertificateManagement #PKI #DatabaseReplication #AzureStorage #DataSecurity #ZeroTrust #AzureSQL #CloudArchitecture #SecurityHardening #DevOps #SysAdmin #CloudOps

Improved Connectivity Types in Azure SQL Managed Instance. As part of its ongoing connectivity overhaul, Azure SQL Managed Instance is removing the last obstacles to broader use of the redirect connection type. The more performant connection type now operates only on port 1433 and provides fallback support for older TDS clients. What are "Proxy" and "Redirect"? Proxy and redirect are two different connectivity mechanisms that can be selected on the instance level to govern SQL client connections on managed instances' VNet-local endpoint. These mechanisms implement two separate data flows between a SQL client and the instance's underlying database engine. When an instance's connection type is set to proxy, an internal gateway component accepts the connection and opens a new one to the primary replica. The gateway then remains involved until the client disconnects, shuttling the data back and forth between the connection from... #techcommunity #azure #microsoft https://lnkd.in/gU89VepX

The .NET team is already planning for .NET 10, and a major change is coming to memory management! Microsoft just detailed the new default Garbage Collector (GC) arriving in the .NET 10 LTS release: DATAS (Dynamic Adaptation To Application Sizes). If you're upgrading from the .NET 8 LTS, this will be a significant new feature for you. For those already on the .NET 9 interim release, you'll have already seen this in action, but now it's becoming the standard for the long-term support channel. Why it matters: ✅ Lower Memory Usage: Perfect for bursty workloads in memory-constrained environments like Kubernetes. ✅ Potential Cost Savings: More efficient memory use can lead to lower cloud hosting bills. ✅ Smarter Resource Management: Adapts to your application's live data size in real-time. It's not a "one-size-fits-all" solution—the article notes that for pure high-throughput scenarios, the classic Server GC might still be the preferred choice. But for most modern services, this is a fantastic step forward. A great read for any .NET developer preparing for the future.

The root cause of recent Dynamo DB service disruption issue was a latent race condition in the DynamoDB DNS management system that resulted in an incorrect empty DNS record for the service’s regional endpoint that the automation failed to repair.
