Microsoft SQL Server features and specs

  • Performance
    Microsoft SQL Server offers high performance and efficient database management capabilities, optimized for both OLTP (Online Transaction Processing) and OLAP (Online Analytical Processing).
  • Security Features
    SQL Server comes with advanced security features such as encryption, data masking, and advanced threat protection to ensure data integrity and privacy.
  • Scalability
    The server supports horizontal and vertical scaling to accommodate growing amounts of data and increasing number of users.
  • Integration with Microsoft Ecosystem
    Seamless integration with other Microsoft products such as Azure, Power BI, and Visual Studio, making it a versatile choice for businesses already using Microsoft services.
  • Ease of Use
    The server provides a user-friendly interface and helpful tools such as SQL Server Management Studio (SSMS) for database maintenance and management.
  • Comprehensive Support
    Microsoft offers extensive support and documentation, along with a strong community that provides additional resources and insights.

Possible disadvantages of Microsoft SQL Server

  • Cost
    Licensing and operational costs can be high, especially for larger enterprises, making it a significant investment.
  • Complexity
    Initial setup and configuration can be complex, often requiring expert knowledge to deploy and maintain effectively.
  • Resource Intensive
    The server can be resource-heavy, requiring significant hardware and computational resources to run efficiently, especially for larger databases.
  • Limited Cross-Platform Support
    Although improvements have been made, SQL Server is primarily optimized for Windows environments, which can limit its use in cross-platform scenarios.
  • Proprietary Software
    Being a proprietary software solution, it lacks the flexibility and cost benefits that come with open-source alternatives.
  • Updates and Patches
    Frequent updates and patches can sometimes disrupt service, requiring periodic maintenance that could result in downtime.

Azure Cosmos DB features and specs

  • Global Distribution
    Azure Cosmos DB allows for the distribution of data across multiple global regions, enhancing availability and delivering low-latency access to data for users around the world.
  • Multi-Model Support
    It supports multiple data models including document, graph, key-value, and column-family APIs, making it versatile for a variety of applications and use cases.
  • Automatic Scaling
    The database automatically scales up and down to meet the demands of application traffic, helping to manage workloads efficiently without manual intervention.
  • High Throughput and Low Latency
    Cosmos DB offers high performance with single-digit millisecond read and write latencies, ensuring fast access to data for applications.
  • Comprehensive SLAs
    Azure Cosmos DB provides industry-leading SLAs covering availability, throughput, consistency, and latency, offering strong guarantees for customers.
  • Integrated Security
    It includes robust security features such as SSL/TLS encryption, role-based access control, and integration with Azure Active Directory for secure data management.

Possible disadvantages of Azure Cosmos DB

  • Cost
    Azure Cosmos DB can be expensive, especially for high-throughput workloads and global distribution scenarios. Its pricing model based on provisioned throughput (RU/s) can add up quickly.
  • Complexity
    Managing and optimizing Cosmos DB can be complex, requiring a deep understanding of its configuration settings, partitioning strategies, and indexing to achieve optimal performance.
  • Vendor Lock-In
    As a proprietary service, using Cosmos DB tightly couples your application to Azure. This can make it difficult to migrate to other database solutions or cloud providers in the future.
  • Consistency Models
    Azure Cosmos DB supports multiple consistency levels which can introduce complexity in designing applications. Developers need to understand and choose the appropriate consistency level for their specific use case.
  • Limited Native Analytics
    Cosmos DB does not have built-in advanced analytics capabilities. Integrating with other services like Azure Synapse or Databricks may be necessary for sophisticated data analytics and reporting.

  • Cloud provider comparison 2024: VM Performance / Price
    Azure is the #2 overall Cloud provider and, as expected, it's the best choice for most Microsoft/Windows-based solutions. That said, it does offer many types of Linux VMs, with quite similar abilities as AWS/GCP. - Source: dev.to / 10 months ago
  • Amdocs, NVIDIA and Microsoft Azure build custom LLMs for telcos
    Amdocs has partnered with NVIDIA and Microsoft Azure to build custom Large Language Models (LLMs) for the $1.7 trillion global telecoms industry. Source: over 1 year ago
  • Windows Azure: Microsoft's crown jewel
    You can utilise various tools on the platform to significantly improve your IT performance. Due to its flexibility, even official recommendations for Azure might need to be clarified and easier to comprehend. Simply put, Azure (formerly Windows Azure) is Microsoft's cloud computing operating system. Source: almost 2 years ago
  • From developer to (solutions) architect. A simple guide.
    This is not to say there aren't architects still working on premise in self managed environments, but if you're planning to join the forces, you probably want to have an idea of who are the 3 public cloud providers (AWS, Azure and GCP), and their offering and topology. - Source: dev.to / almost 4 years ago
  • Can You Learn AWS (And Get Certified) With No Experience? e.g. No IT background or degree
    Right now, AWS couldn’t be a better choice. AWS has been for many years—and continues to be—the market leader between all the cloud platforms. Whilst the competitors like GCP and Azure are catching up, they’ve still not toppled AWS which continues to be, by far, the biggest cloud provider. - Source: dev.to / over 4 years ago

  • Blazor server app, deployment options
    If you are writing the code maybe consider learning Cosmos DB it’s pretty easy to work with and there is a free tier. Also in my experience it’s much faster than a SQL database. Source: about 2 years ago
  • Infrastructure as code (IaC) for Java-based apps on Azure
    Sometimes you don’t need an entire Java-based microservice. You can build serverless APIs with the help of Azure Functions. For example, Azure functions have a bunch of built-in connectors like Azure Event Hubs to process event-driven Java code and send the data to Azure Cosmos DB in real-time. FedEx and UBS projects are great examples of real-time, event-driven Java. I also recommend you to go through 👉 Code,... - Source: dev.to / almost 3 years ago
  • Deploying a Mostly Serverless Website on GCP
    When debating the database solution for our application we were really seeking for a scalable serverless database that wouldn’t bill us for idle time. Options like AWS Athena, AWS Aurora Serverless, and Azure Cosmos DB immediately came to mind. We believed that GCP would have a comparable service, yet we could not find one. Even after consulting the GCP cloud service comparison documentation we were still unable... - Source: dev.to / almost 3 years ago

  • Basic Setup for Azure Cosmos DB and Example Node App
    I have had an opportunity to work on a project that uses Azure Cosmos DB with the MongDB API as the backend database. I wanted to spend a little more time on my own understanding how to perform basic setup and a simple set of CRUD operations from a Node application, as well as construct an easy-to-follow procedure for other developers. - Source: dev.to / about 3 years ago
