Microsoft Azure is a set of cloud services that can help your business achieve fearless growth. No matter how big or small your company, Azure can provide you with the freedom to build, manage and deploy apps using your favourite tools and frameworks. Azure offers a range of functionalities including, analytics, storage, computing, networking and more – all of which integrates with your cloud environment to help you achieve fearless growth. Azure Create a hybrid cloud environment with ease,It has a comprehensive set of compliance offerings,Covers more global regions than any other cloud provider.
Security is a big concern to many businesses, especially in the cloud. Azure and AWS are two of the biggest cloud providers, and both have thecapabilities of making sure your cloud environment is secure.
Microsoft has created their own version of role-based access control (RBAC) called Azure Directory. RBAC will help you enhance and simplify security as you control users’permissions. Thanks to Microsoft background on networking, they’ve been able to develop a complex and strong security feature that will allow you to manage users access successfully.
The following are some important aspects wherein Azure scores over AWS.
Many of the same principles that apply to AWS can also apply to Azure, but Azure Network Security Groups (NSG) have a few important differences:
NSGs can be applied to individual VMs, subnets, or both
NSGs have both ‘Deny’ and ‘Allow’ rules – This means that rule order (or priority) matters!
Like EC2 Classic Security Groups, Azure NSGs can only be applied to resources in the same region they were created in
Azure has a security feature called Endpoint ACLs, you can’t have both an NSG and an endpoint ACL applied to the same VM
All NSGs include a set of default rules that cannot be changed or deleted, but can be overridden
Like AWS Security Groups, Azure NSGs have two sets of rules, inbound and outbound.
Each rule has the following properties:
Priority – A best practice will be to use large increments (100,200) so you won’t have to edit the priorities of existing rules when adding new ones
Source – Any/CIDR block/Tag (Tags are explained below)
Protocol – TCP/UDP/Any
Source Port – Range/Single Port/Any
Destination – Any/CIDR block/Tag (Tags are explained below)
Destination Port – Range/Single Port/Any
Action – Allow/Deny
Microsoft Azure has two deployment models, Classic and Resource Manager. Simply put, old and new. The two deployment models are different approaches for using the Azure cloud platform, and they handle resource provisioning differently. I highly recommend reading more about the differences between Resource Manager and Classic.
In Classic Deployments – NSGs are applied to VMs. This means that the NSG rules will apply to all traffic coming to and going from the VM.
In Resource Manager Deployments – NSGs are applied to NICs. This means that the NSG rules will only apply to the relevant NIC. In a multi-NIC machine, the NSG will not process traffic from other NICs unless configured on them.
In both deployments – NSGs can be applied to subnets. This means that the NSG rules will be applied to all NICs that belong to that subnet.
Azure and AWS for Microsoft stores
Microsoft has long been synonymous with big business. Microsoft Azure facilitates cloud migration for users who currently use Windows Server, SQL Server, Exchange, and other Microsoft technologies.
For .NET developers, publishing applications on Azure is surprisingly simple. Publishing your app on Azure App Services or Cloud Services eliminates all the headaches associated with deploying applications and managing servers.
For Microsoft stores, Azure has a big advantage. However, AWS supports Windows, SQL Server, and other technologies used by .NET developers.
Azure and AWS for Open Source Developers
Amazon may have started as an online vendor, but Microsoft has always looked for Windows-based business customers and similar platforms. Azure will continue this relationship with enterprise users by providing seamless integration with Visual Studio and integration with Active Directory. You can also connect to the Azure platform and Office 365 using your current Active Directory account.
EXPERTISE At Dalwax, we’ve tackled several challenging Azure transformation journeys for our customers, by re-architecting and rewriting their applications from the ground up to be Azure-native. Along the way, we learned some key lessons on how to re-architect applications to be modular, scalable, fault tolerant and ultra-responsive.
PaaS & Container Architectures
We are experts at converting traditional stateful applications into modern applications leveraging Azure PaaS services and container architectures for total control over scalability and resilience.
While modernizing applications we leverage an Agile DevOps driven approach that enables application delivery transformation by enabling toolchains and processes that support continuous integration and continuous delivery.
We can help develop and implement best-fit architectures and components depending on whether your application is heavy on end-user interactions (predominantly user driven and UI / UX is important) vs Event driven (IoT and business process automation Intelligent apps).
Corporate compliance, governance and performance considerations can mandate application components to remain within Private cloud or existing on-premise environments, and still talk to the Public cloud components. Our experts can help design solutions for optimal performance and scale.
While monolithic, on-premise applications are perceived to be secure due to the ability to implement centralized security policies while behind corporate firewalls, with our knowledge and expertise we can help deploy enhanced security postures within your Azure cloud environments.
We can help businesses efficiently leverage ready-to-use Azure cloud services and solution components to reduce development time while benefitting from the inherent cloud native features of the services. Our experts strike the right balance between upfront vs ongoing benefits of using these services.
