Azure VS On Premise Pros & Cons

There are a lot of good reasons for enterprises to move to the cloud, such as greater business agility, keeping track with the speed of innovation, and cost savings. The current state of the various cloud surveys shows that cloud adoption is growing and has now hit its stride. The strong growth in the use of cloud means that the majority of organizations are now operating in a hybrid environment that consists of on-premises and cloud-based services.


Azure infrastructure includes hardware, software, networks, administrative and operations staff, and the physical datacenters that house it all. Azure addresses security risks across its infrastructure.

Physical security

Azure runs in geographically distributed Microsoft facilities, sharing space and utilities with other Microsoft Online Services. Each facility is designed to run 24x7x365 and employs various measures to help protect operations from power failure, physical intrusion, and network outages. These datacenters comply with industry standards (such as ISO 27001) for physical security and availability. They are managed, monitored, and administered by Microsoft operations personnel.

Monitoring & Logging

Centralized monitoring, correlation, and analysis systems manage the large amount of information generated by devices within the Azure environment, providing continuous visibility and timely alerts to the teams that manage the service. Additional monitoring, logging, and reporting capabilities provide visibility to customers.

Update Management

Security update management helps protect systems from known vulnerabilities. Azure uses integrated deployment systems to manage the distribution and installation of security updates for Microsoft software. Azure uses a combination of Microsoft and third-party scanning tools to run OS, web application, and database scans of the Azure environment.

Antivirus & Antimalware

Azure software components must go through a virus scan prior to deployment. Code is not moved to production without a clean and successful virus scan. In addition, Microsoft provides native antimalware on all Azure VMs. Microsoft recommends that customers run some form of antimalware or antivirus on all virtual machines (VMs). Customers can install Microsoft Antimalware for Cloud Services and Virtual Machines or another antivirus solution on VMs, and VMs can be routinely reimaged to clean out intrusions that may have gone undetected.

Penetration Testing

Microsoft conducts regular penetration testing to improve Azure security controls and processes. Microsoft understands that security assessment is also an important part of our customers’ application development and deployment. Therefore, Microsoft has established a policy for customers to carry out authorized penetration testing on their own and only their own applications hosted in Azure.

DDoS Protection

Azure has a defense system against Distributed Denial-of-Service (DDoS) attacks on Azure platform services. It uses standard detection and mitigation techniques. Azure’s DDoS defense system is designed to withstand attacks generated from outside and inside the platform.

If we talking about cons Internet connectivity  is considered as one of the biggest potential downsides of using Cloud Computing. Running all or some of your business applications in the cloud is great, as long as you can maintain a consistent Internet connection. If any one of your cloud-based service providers loses connectivity, or if your ISP experiences an outage, you’re out of business until that Internet connection returns. Even the best servers go down occasionally, so if you decide to use this method, it’s important to implement a backup plan
