Windows Azure Platform is the cloud offering from Microsoft that encompasses many independent services for compute, storage, networking, monitoring and reporting among others. IT professionals searching for ways to subscribe and manage a Windows Azure subscription should look no further. This Windows Azure tutorial series brings you a step by step easy method to access the Windows Azure Platform. As part of the first installment of our Windows Azure tutorial, we will discuss how to set up end user access to the Windows Azure Platform.
Azure is a new cloud computing platform under development by Microsoft (microsoft.com/windowsazure). Cloud computing allows developers to host applications in an Internet-accessible virtual environment. The environment transparently provides the hardware, software, network and storage needed by the application.
Cloud Computing, SOA and Windows Azure – Part 1
The WS model of SOA has never been widely accepted or adopted, in part because of its inherent complexity, but also because of the incompatibility between the WS approach and the RESTful API model of the internet. The internet, and the related cloud computing model, exposed specific issues with SOA/WS, and overall, the industry has moved to a different model.
Microservices can be shared among applications, and cloud providers may offer serverless pay-as-you-use models for microservice hosting. In these cases, there may be a formal commercial microservice or service contract to describe the specific performance guarantees and the payment terms. Even internal microservices may have a contract if the IT organization charges departments back for usage.
Explanation: It is the front-end that refers to the user's part of the cloud computing system. It includes many applications and interfaces that are required to access or use the cloud computing platform.
This paper presents the Forecast-as-a-Service (FaaS) framework, a cloud-based framework that provides on-demand customer-defined forecasting services. Based on the principles of service-oriented architecture (SOA), the FaaS enables the use of different types of data from different sources to generate different kinds of forecasts at different levels of detail for different prices. The FaaS framework has been developed to provide on-demand forecasts of solar or wind power. Forecasts can be long-term forecasts useful for prospecting or planning by potential investors, or short-term forecasts suitable for operational decision making by operators of existing facilities. FaaS provides a more flexible and affordable alternative to the subscription model provided by current forecast service vendors. By improving the flexibility and economics of renewable energy forecasting services with SOA and cloud computing, FaaS achieves the goal of Services Computing.
Azure Service Bus is a fully managed multi-tenant cloud messaging service (MAAS). It is brokered messaging system. Applications and services can communicate with each other using messages via Service Bus. Message consists of two parts; message properties and message payload. Message properties is a dictionary of values against property keys. Message payload is in binary format, which can contain JSON, XML, or text data.
This one partially migrates some of the systems components to the cloud. There are quite few papers on the partial migration where the organizations have migrated one or more application layer implementing a particular functionality in the cloud.
Cloud service can convey multiple web applications in Azure, characterizing a number of parts to disseminate handling and permit adaptable scaling of your application. A cloud service comprises a minimum of one web part, as well as specialist parts, each with its own particular application documents and design. The fundamental favorable position of cloud service is the capacity to help more complex multilevel structures.
Cloud is essentially a series of servers that might be accessed through the web, and all one piece of information is stored on physical servers in information centers. Intrinsically by cloud computing, we can access the physical servers and run computer code applications on their machines.
Software as a service (SaaS) is a software distribution model in which a third-party provider hosts applications and makes them available to their customers over the Internet. SaaS is one of three main categories of cloud computing, alongside infrastructure as a service (IaaS) and platform as a service (PaaS).
The primary objective is to deliver internet services in a public or private cloud. Unlike a private cloud, public cloud services are third-party applications that can be used by anybody who wants to access them. The service may be free or sold on demand.Public clouds are open to people for use and deployment. For example, Google and Amazon, etc. The public clouds focus on a few layers like cloud application, providing infrastructure, and providing platform markets.
A hybrid cloud is a cloud computing environment where we can use the services available locally and use third-party private and public services to meet the demand. By allowing workloads to move between private and public clouds as computing needs and costs change, a hybrid cloud gives businesses greater flexibility and more data deployment options.
Data security: As data develops, data breaching becomes a significant issue, and the servers become soft targets. The security solution of cloud data helps protect sensitive information and helps the data stay secure against a third party.
Eucalyptus is an open-source software infrastructure in cloud computing, enabling us to implement clusters in the cloud computing platform. The main application of eucalyptus is to build public, hybrid, and private clouds. Using this, you can produce your personalized data center into a private cloud and leverage it for various other organizations to make the most out of it and use the functionalities offered by eucalyptus.
Distributed computing visualizes the idea of connecting multiple computers through computer networks by using a distributed system. These computers can be different and the same and are located globally also. Distribute Computing consists of various parts: grid, clusters, web 2.0, and clouds. Clusters can be defined as multiple servers grouped to provide computing services to users.
Various factors are responsible for advantageous cloud computing, including improved scalability, excellent accessibility, mobility, storage, etc. Cloud Computing still has security issues and are given below:
Interfaces through which we can connect to the internet for most cloud services as APIs and interfaces are connected to cloud services through third parties. Hackers can quickly attack them as they are in the public domain.
Cloud computing is a rapidly evolving technology in terms of speed, scalability, and efficiency. This is mainly happening thanks to open-source software becoming an integral part of the cloud. Just to name a few, your candidate should be familiar with MongoDB, CouchDB, and LucidDB. The first one, MongoDB, is written in C++ and offers high storage capabilities. Also, this database system is schema-free and document-oriented. On the other hand, CouchDB is based on an Apache server and is very efficient and reliable at its job (which is storing data). Finally, we find LucidDB, employed for data warehousing, and it is written in Java/C++.
This complex question requires a complex answer: thanks to utility computing, the end-user will only have to pay for the service on a per-use basis. The user will be able to increase the number of services he uses to satisfy his needs. This approach to cloud computing can be very remunerative for those businesses that plan to scale and grow their product.
Infrastructure as Code (IaC) is an integral part of modern continuous integration pipelines. It is the process of managing and provisioning cloud and IT resources using machine readable definition files. IaC gives organizations tools to create, manage, and destroy compute resources by statically defining and declaring these resources in code.
Service Level Agreements are based on the usage model. Frequently, cloud providers charge their pay-as-per-use resources at a premium and deploy standards Service Level Agreements only for that purpose. Clients can also subscribe at different levels that guarantees access to a particular amount of purchased resources. The Service Level Agreements (SLAs) attached to a subscription many times offer various terms and conditions. If client requires access to a particular level of resources, then the client need to subscribe to a service. A usage model may not deliver that level of access under peak load condition. 2ff7e9595c
