Cloud vendor lock-in is one of
the major problems in cloud computing where the
customer is locked to a particular vendor so that it
will be difficult to migrate from one cloud to the
other. The problem is that once an app has been
developed based on a particular cloud service
provider’s API that apps is bound to that provider
as a result of which migration from one cloud to
the other becomes more complex because of
changes in architectures of different cloud service
vendors[2]. The problem can be solved by
providing a standardized way of interacting with
cloud service providers taking many factors into
consideration and by isolating each individual
module involved in the cloud service provider’s
API and bringing out the common things and
uniting them together so that in future any CSP
will have to obey that specific standards and build
their APIs without the need of creating a new
standard that makes migration from/to that CSP
complex.

Virtualization abstracts physical computing resources into virtual resources that can be allocated dynamically. It allows for server consolidation, improved system management, increased application availability, and more efficient use of resources. There are different types of virtualization including server, storage, and network virtualization. Server virtualization uses a virtual machine monitor to run multiple virtual machines on a single physical machine. Storage virtualization presents a logical view of physical storage to improve utilization and manageability. Trap-and-emulate is a common approach for virtualizing the system instruction set architecture by having privileged instructions trap to an emulator.
ZENworks Application Virtualization for NGN DummiesRoel van Bueren
The document provides an agenda and overview for a training on ZENworks Application Virtualization (ZAV).

It also covers ZAV configuration options, interactions with the operating system, variables, sandboxing, and integration with Novell ZENworks Configuration Management (ZCM).
An Azure virtual network (VNet) provides connectivity and security for virtual machines and allows access to the public internet and other VMs. Network security groups contain rules that allow or deny network traffic, and Azure load balancers distribute incoming internet traffic across VMs. Availability sets distribute VMs across update and fault domains for redundancy and high availability. Virtual network gateways connect Azure VNets and on-premises networks, while Traffic Manager controls traffic distribution across endpoints in different datacenters.
Virtualization allows organizations to reduce hardware costs and improve efficiency by running multiple virtual machines on a single physical server. This allows applications to be isolated from one another while sharing common resources. Virtualization provides benefits like faster deployment times, reduced maintenance costs, increased availability, and better performance. While virtualization introduces dependencies on vendors, it provides clear returns on investment for testing environments through lower costs and faster setup times.
Virtualization refers to creating virtual versions of hardware resources like storage, memory, and network instead of using actual physical resources. It allows multiple operating systems and applications to run simultaneously on a single host computer. There are different levels of virtualization including application layer, library/programming level, operating system level, hardware abstraction layer level, and instruction set architecture level. Each level has advantages and disadvantages in terms of performance, compatibility, and complexity. Popular tools for managing and monitoring virtualization environments include VMware vCenter, Microsoft System Center VMM, and Citrix XenCenter.
This document provides information on virtualization techniques including full virtualization and paravirtualization. Full virtualization uses binary translation and direct execution to simulate hardware and allow unmodified guest operating systems to run in isolated virtual machines. Paravirtualization modifies the guest operating system kernel to use hypercalls to communicate with the hypervisor more efficiently. The document also compares virtualization and containerization, noting that virtualization simulates full hardware while containerization isolates at the operating system level for lighter resource usage.
Virtualization: Force driving cloud computingMayank Aggarwal
Virtualization allows a single physical machine to run multiple virtual machines, making hardware resources available to multiple virtual operating systems. This is done through a hypervisor or virtual machine monitor that allocates physical resources to virtual machines. Virtualization provides benefits like reduced costs, increased hardware utilization, and isolation of environments while sharing resources. The main types of virtualization are execution level (using a hypervisor), operating system level (through time-sharing), programming level (through virtual machines like Java), application level, storage, and network.

Developers must consider how stateful or stateless their web services are when deploying in a clustered environment like a server farm. Stateless services are easier to scale by adding nodes and have higher performance as they don't require preserving state between requests. If services are stateful, the service or middleware must handle failover and reconstructing state when requests are routed to different nodes.

Monitoring the Execution of 14K Tests: Methods Tend to Have One Path that Is ...Andre Hora
The literature has provided evidence that developers are likely to test some behaviors of the program and avoid other ones. Despite this observation, we still lack empirical evidence from real-world systems. In this paper, we propose to automatically identify the tested paths of a method as a way to detect the method’s behaviors. Then, we provide an empirical study to assess the tested paths quantitatively. We monitor the execution of 14,177 tests from 25 real-world Python systems and assess 11,425 tested paths from 2,357 methods. Overall, our empirical study shows that one tested path is prevalent and receives most of the calls, while others are significantly less executed. We find that the most frequently executed tested path of a method has 4x more calls than the second one. Based on these findings, we discuss practical implications for practitioners and researchers and future research directions.

1. High Availability of Azure
Applications(PaaS)
Himanshu Sahu
Mindfire Solutions
himanshus@mindfiresolutions.com
2. Agenda
Introduction
Windows Azure Role Architecture
Fault Domains in Windows Azure
Update Domains in Windows Azure
Windows Azure Host OS Updates
Windows Azure Guest OS Updates
Techniques for High Availability
3. High Availability in Azure
Introduction
ALWAYS ON
Reliability and Scalability
Design for failure
Implement separation of function
Use a service-oriented architecture
5. Fault Domains in Windows Azure
Fault Domains
Fault Domain is a physical unit of failure, and is closely related to
the physical infrastructure in the data centers. In Windows Azure
the rack can be considered a fault domain. However there is no 1:1
mapping between fault domain and rack.
Windows Azure Fabric is responsible to deploy the instances of
your application in different fault domains. Right now Fabric makes
sure that your application uses at least 2 (two) fault domains.
As a developer have no direct control over how many fault
domains your application will use.
6. Update Domains in Windows Azure
Update Domains
Upgrade Domain is a logical unit, which determines how particular
service will be upgraded.
The default number of upgrade domains that are configured for
your application is 5 (five). You can control how many upgrade
domains your application will use through the upgradeDomain
configuration setting in your service definition file (CSDEF).
7. Windows Azure Host Updates
When and Why
Windows Azure deploys updates to the host OS approximately
once per month. This ensures that Windows Azure provides a
reliable, efficient and secure platform for hosting your applications.
The HA consists of multiple subcomponents, such as the Network
Agent (NA) that manages virtual machine VLANs and the Virtual
Machine virtual disk driver that connects Virtual Machine disks to
the blobs containing their data in Windows Azure Storage. Azure
therefore update the HA and its subcomponents at different
intervals, depending on when a fix or new functionality is ready.
9. Windows Azure Host Updates
How
The host OS reboots instances and the fabric controller ensures that only
instances from one upgrade domain at a time will be rebooted.
Virtual machines running on the server that have an Input Endpoint in
their role’s service model are removed from the load balancer rotation so
that no new requests will come to the virtual machine and instead new
requests are sent to other instances of that role as per the Azure load-
balancing policies.
Each virtual machine hosting a Web or Worker Role receives a Stopping
event, whereas VM Roles receive a standard Windows shutdown event.
Worker, Web, and Virtual machine roles are allowed five minutes to
respond to the stopping and shutdown event before they are forcibly
stopped.
10. Windows Azure Host Updates
How
After all guest virtual machines are stopped, the root partition OS
shuts down and the server reboots.
The updated root partition OS starts.
The virtual machines hosted on the server boot and start their
application code.
Virtual machines hosting service roles with Input Endpoints
reconnect to the load balancer, enabling them to receive client
request
11. Windows Azure Guest Updates
Once the Host OS has finished upgrading across the datacenter
then the Guest OS will be upgraded for services which are
configured to use automatic Guest OS versions and this upgrade
will proceed using standard upgrade domain rules for your service.
Your VM will be rebooted and the Windows Partition (the D drive)
will be reimaged with the upgraded OS.
The Guest OS update process is much faster than the Host OS
update since the fabric only has to coordinate the update within
your hosted service and your upgrade domains.
12. Availability
An available application considers the availability of its underlying
infrastructure and dependent services. Available applications
remove single points of failure through redundancy and resilient
design
Azure SLA
More Instances in Azure
Make Guest OS Update Manual
13. Availability
Scalability directly affects availability—an application that fails
under increased load is no longer available. Scalable applications
are able to meet increased demand with consistent results in
acceptable time windows.

Protection against hardware failures
Because every application is made up of multiple instances of each
role, hardware failures—a disk crash, a network fault, or the death
of a server machine—won’t take down the application. To help
with this, the fabric controller doesn’t choose machines for an
application’s instances at random. Instead, different instances of
the same role are placed in different fault domains. A fault domain
is a set of hardware—computers, switches, and more—that share a
single point of failure. (For example, all of the computers in a single
fault domain might rely on the same switch to connect to the
network.) Because of this, a single hardware failure can’t take
down an entire application. The application might temporarily lose
some instances, but it will continue to behave correctly.

Protection against software failures
The fabric controller can also detect failures caused by software. If
the code in an instance crashes or the VM in which it’s running
goes down, the fabric controller will start either just the code or, if
necessary, a new VM for that role. While any work the instance
was doing when it failed will be lost, the new instance will become
part of the application as soon as it starts running.

The ability to update applications with no application
downtime
When a new version of the application needs to be deployed, the
fabric controller can shut down the instances in just one update
domain, update the code for these, then create new instances
from that new code. Once those instances are running, it can do
the same thing to instances in the next update domain, and so on.
While users might see different versions of the application during
this process, depending on which instance they happen to interact
with, the application as a whole remains continuously available.
