Introducing IoT Hub device streams in public preview

Azure IoT Hub device streams is a new PaaS service that addresses the need for security and organization policy compliance by providing a foundation for secure end-to-end connectivity to IoT devices. At its core, an IoT Hub device stream is a data transfer tunnel that provides connectivity between two TCP/IP-enabled endpoints: one side of the tunnel is an IoT device and the other side is a customer endpoint that intends to communicate with the device. IoT Hub device streams address end-to-end connectivity needs by leveraging an IoT Hub cloud endpoint that acts as a proxy for application traffic exchanged between the device and service. IoT Hub device streams are particularly helpful when devices are placed behind a firewall or inside a private network.

Announcing the preview of OpenAPI Specification v3 support in Azure API Management

Azure API Management has just introduced preview support of OpenAPI Specification v3 – the latest version of the broadly used open-source standard of describing APIs. We based the implementation of this feature on the OpenAPI.NET SDK. OpenAPI Specification is a widely-adopted industry standard that enables you to abstract your APIs from their implementation in a language-agnostic and easy to understand format. The wide adoption of OpenAPI Specification (formerly known as Swagger) resulted in an extensive tooling ecosystem.  If your APIs are defined in an OpenAPI Specification file, you can easily import them in Azure API Management (APIM). APIM helps organizations publish APIs to external, partner, and internal developers to unlock the potential of their data and services. Once the backend API is imported into APIM, the APIM API becomes a façade for the backend API.

Regulatory compliance dashboard in Azure Security Center now available

The regulatory compliance dashboard in Azure Security Center (ASC) provides insight into your compliance posture for a set of supported standards and regulations, based on continuous assessments of your Azure environment. The ASC regulatory compliance dashboard is designed to help you improve your compliance posture by resolving recommendations directly within the dashboard. Click through to each recommendation to discover its details, including the resources for which the recommendation should be implemented. The regulatory compliance dashboard preview is available within the standard pricing tier of Azure Security Center, and you can try it for free for the first 30 days.

Public preview: Read replicas in Azure Database for PostgreSQL

You can now replicate data from a single Azure Database for PostgreSQL server (master) to up to five read-only servers (read replicas) within the same Azure region. This feature uses PostgreSQL's native asynchronous replication. With read replicas, you can scale out your read-intensive workloads. Read replicas can also be used for BI and reporting scenarios. You can choose to stop replication to a replica, in which case it becomes a normal read/write server. Replicas are new servers that can be managed in similar ways as normal standalone Azure Database for PostgreSQL servers. For each read replica, you are billed for the provisioned compute in vCores and provisioned storage in GB/month.

Azure Service Bus and Azure Event Hubs expand availability

Availability Zones is a high availability offering that protects applications and data from datacenter failures. Availability Zones support is now generally available for Azure Service Bus premium and Azure Event Hubs standard in every Azure region that has zone redundant datacenters. Note that this feature won’t work with existing namespaces—you will need to provision new namespaces to use this feature.  Availability Zones support for Azure Service Bus Premium and Azure Event Hubs Standard is available in the following regions: East US 2, West US 2, West Europe, North Europe, France Central, and Southeast Asia.

Azure Cognitive Services adds important certifications, greater availability, and new unified key

Over the past six months, we added added 31 certifications across services in Cognitive Services and will continue to add more in 2019. With these certifications, hundreds of healthcare, manufacturing, and financial use cases are now supported. In addition, Cognitive Services now offers more assurances for where customer data is stored at rest. These assurances have been enabled by graduating several Cognitive Services to Microsoft Azure Core Services. Also, the global footprint for Cognitive Services has expanded over the past several months — going from 15 to 25 Azure data center regions. Recently, we launched a new bundle of multiple services, enabling the use of a single API key for most of our generally available services: Computer Vision, Content Moderator, Face, Text Analytics, Language Understanding, and Translator Text.

Microsoft and Citus Data: Providing the best PostgreSQL service in the cloud

On Thursday, Microsoft  announced the acquisition of Citus Data, an innovative open source extension to scale out PostgreSQL databases without the need to re-architect existing applications. Citus Data delivers unparalleled performance and scalability by intelligently distributing data and queries across multiple nodes, which makes sharding simple. Because Citus Data is packaged as an extension (not a fork) to PostgreSQL, customers can take advantage of all the innovations in community PostgreSQL with queries that are significantly faster compared to proprietary implementations of PostgreSQL. More information is available in this post by Rohan Kumar, Corporate Vice President, Azure Data: Microsoft acquires Citus Data, re-affirming its commitment to Open Source and accelerating Azure PostgreSQL performance and scale.

HDInsight Metastore Migration Tool open source release now available

Microsoft Azure HDInsight Metastore Migration Tool (HMMT) is an open-source shell script that you can use for applying bulk edits to the Hive metastore. HMMT is a low-latency, no-installation solution for challenges related to data migrations in Azure HDInsight. This blog post covers how HMMT is outlined with respect to the Hive metastore and Hive storage patterns, the design of HMMT and describes initial setup steps, and finally, some sample migrations are described and solved with HMMT as a demonstration of its usage and value.

Azure Backup now supports PowerShell and ACLs for Azure Files

Azure Backup now supports preserving and restoring new technology file system (NTFS) access control lists (ACL) for Azure files in preview. You can now script your backups for Azure File Shares using PowerShell. Make use of the PowerShell commands to configure backups, take on-demand backups, or even restore files from your file shares protected by Azure Backup. Using the “Manage backups” capability in the Azure Files portal, you can take on-demand backups, restore files shares, or individual files and folders, and even change the policy used for scheduling backups. You can also go to the Recovery Services Vault that backs up the file share and edit policies used to backup Azure File shares. Backup alerts for the backup and restored jobs of Azure File shares are enabled, which enables you to configure notifications of job failures to chosen email addresses.

Security for healthcare through cloud agents and virtual patching

For a healthcare organization, security and protection of data is a primary value, but solutions can be attacked from a variety of vectors such as malware, ransomware, and other exploits. The attack surface of an organization could be complex, email and web browsers are immediate targets of sophisticated hackers. One Microsoft Azure partner, XentiT (ex-ent-it), is devoted to protecting healthcare organizations despite the complexity of the attack surface. XentIT leverages two other security services with deep capabilities and adds its own expertise to create a dashboard-driven security solution that lets healthcare organizations better monitor and protect all assets.
