Account credentials are a major cloud security issue because vulnerability scanners or penetration testing can’t determine if they’ve been compromised or if they’re being abused by attackers.
Compromised credentials become a problem when they are used. If someone shared cloud authentication credentials(for an example an employee left the company and never used the credentials, the organization might never discover the exposure).
Another example like multiple attempts to log in simultaneously from geographical locations could also compromise the cloud security according to experts.
Below a study from Juniper networks
A virtual private server (VPS) is a virtual machine service by an Internet hosting service.
It allows developers migrate applications and infrastructure without changing existing code and can run both Windows Server and Linux virtual machines. Announced in preview form at the Meet Windows Azure event in June 2012 the Windows Azure Virtual Machines comprise the Infrastructure as a Service (IaaS) offering from Microsoft for their public cloud. Customers can create Virtual Machines, of which they have complete control, to run in the Microsoft Data Centers. As of the preview the Virtual Machines supported Windows Server 2008 and 2012 operating systems and a few distributions of Linux. The General Availability version of Virtual Machine was released in May 2013.
Amazon Virtual Private Cloud (Amazon VPC)
Amazon VPC is isolated section of the Amazon Web Services (AWS) Cloud where can launch AWS resources in a virtual network, including own IP address range, subnets, route tables and network gateways .Also can create a Hardware Virtual Private Network (VPN) connection between a corporate datacenter and VPC.
For example, a public-facing subnet for your web servers that have access to the Internet, and place your backend systems such as databases or application servers in a private-facing subnet with no Internet access. You can leverage multiple layers of security, including security groups and network access control lists, to help control access to Amazon EC2 instances in each subnet.

With Amazon EC2, you can place instances in multiple locations. Amazon EC2 locations are composed of regions that contain Availability Zones. Regions are dispersed and located in separate geographic areas (US, EU, etc.). Availability Zones are distinct locations within a region that are engineered to be isolated from failures in other Availability Zones and to provide inexpensive, low-latency network connectivity to other Availability Zones in the same region. By launching instances in separate regions, you can design your application to be closer to specific customers or to meet legal or other requirements. By launching instances in separate Availability Zones, you can protect your applications from localized regional failures. The AWS region name is always listed in the upper-right corner of the AWS Management Console, in the navigation bar.
