Availabilityįrom an availability point of view, the AWS RDS SQL Server service offers a tier without High availability (with no SLA) and another with a single standby server. The method allows Azure Platform to move databases transparently when it is necessary, such as environment upgrades. While the gateway approach seems unnecessary at first glance, it offers management and scalability capabilities that are only possible in this architecture. This connectivity model does not apply to Managed Instances, which uses direct DNS name connectivity (similar to AWS). However, this gateway routing architecture can also have a noticeable negative impact on applications that require fast response times. It means that the primary database can be hosted on any server at any point in time. Therefore, the azure Single Databases service needs a gateway mechanism to correctly identify which database your application is attempting to connect to, and on which server. On the other end, Azure single databases can be deployed on the same server, coexisting with other customer databases with a high degree of isolation (ensuring security). It mirrors what most developers would expect in a traditional data center design. The databases cloud services offer a different connectivity architecture.ĪWS RDS SQL Server uses direct connectivity. Regarding the prices, compare them is a challenge because the services are not directly analogous.Īnyway, Azure SQL Databases and Amazon AWS RDS have tools to help you estimate the costs. Microsoft Azure model drives you into a VM implementation, if you need to use old versions of SQL Server. However, the AWS RDS service gives organizations more flexibility, since some legacy applications cannot always run on more modern database engines. There are two implementations for Azure SQL Database – Singles instance/Elastic pools and Managed Instance.Īmazon offers a mostly version oriented model (actually, from 2012 to 2017) in a dedicated instance.ĪWS allows you to choose which version and edition (express, web, standard, and enterprise) to use. Microsoft ensures that your application always runs on the latest binaries available (SQL Server 2019), including the newest features available. Offeringsīoth offerings are considered Platform as a Service (PaaS) implementations. In this post, we’ll see a high-level of each cloud service differences and guide you to choose the best service for your business. However, it’s essential to compare the features, advantages, and limitations between them before you decide on an Amazon AWS or Azure migration. Many companies use both to enjoy each Cloud’s unique feature set. The database itself would remain inaccessible from the internet.Amazon AWS and Microsoft Azure are excellent options for deploying MS SQL Server databases. You could then open up a port in the security group to allow access to the Web API application from the internet. So, if you had an EC2 instance (running Windows/Linux) and a SQL Server in the same VPC there would be no problem deploying a Web API application to the EC2 instance and querying the SQL Server from there. A little backgroundīy default, resources created inside a VPC are inaccessible from the internet but can be accessed from inside the VPC. The SQL Server will be seeded with data, and the function will be accessible from anywhere in the world. NET 6 Web API application, deployed to a Lambda function, querying a SQL Server inside your VPC that is not publicly accessible. The process for doing this is not hard, but there are a few steps.īy the end of this post, you will have a. Accessing an Amazon RDS SQL Server from a Lambda function (I will sometimes refer to this by the word “function”) doesn’t work out of the box, the function needs access to the Virtual Private Cloud (VPC) the SQL Server is in.
