Cloud computing has evolved and diversified into a wide array of offerings and capabilities designed to suit almost any conceivable business need. Examples of cloud computing capabilities and diversity include the following:
While the big cloud vendors would be very happy to provide all the computing needs of their enterprise customers, increasingly businesses are looking to spread the load across a number of suppliers. All of this has lead to the rise of multi-cloud. Part of this approach is to avoid being locked in to just one vendor (which can lead to the sort of high costs and inflexibility that the cloud is often claimed to avoid), and part of it is to find the best mix of technologies across the industry.

Cloud computing is reaching the point where it is likely to account for more of enterprise tech spending than the traditional forms of delivering applications and services in-house that have been around for decades. However, use of the cloud is only likely to climb as organisations get more comfortable with the idea of their data being somewhere other than a server in the basement. And now cloud-computing vendors are increasingly pushing cloud computing as an agent of digital transformation instead of focusing simply on cost. Moving to the cloud can help companies rethink business processes and accelerate business change, goes the argument, by helping to break down data any organisational silos. Some companies that need to boost momentum around their digital transformation programmes might find this argument appealing; others may find enthusiasm for the cloud waning as the costs of making the switch add up.
Cloud computing is the on-demand delivery of IT resources over the Internet with pay-as-you-go pricing. Instead of buying, owning, and maintaining physical data centers and servers, you can access technology services, such as computing power, storage, and databases, on an as-needed basis from a cloud provider like Amazon Web Services (AWS).
Formerly known as Windows Azure, Microsoft Azure is a public cloud computing platform that provides a range of cloud services for computing, storing, and networking. Depending upon your requirements, you can manage and store data.
First, you need to determine the type of cloud deployment, or cloud computing architecture, that your cloud services will be implemented on. There are three different ways to deploy cloud services: on a public cloud, private cloud, or hybrid cloud. Learn more about public, private, and hybrid clouds.
Platform as a service refers to cloud computing services that supply an on-demand environment for developing, testing, delivering, and managing software applications. PaaS is designed to make it easier for developers to quickly create web or mobile apps, without worrying about setting up or managing the underlying infrastructure of servers, storage, network, and databases needed for development.
Cloud computing operates on a similar principle as web-based email clients, allowing users to access all of the features and files of the system without having to keep the bulk of that system on their own computers. In fact, most people already use a variety of cloud computing services without even realizing it. Gmail, Google Drive, TurboTax, and even Facebook and Instagram are all cloud-based applications. For all of these services, users are sending their personal data to a cloud-hosted server that stores the information for later access. And as useful as these applications are for personal use, they're even more valuable for businesses that need to be able to access large amounts of data over a secure, online network connection.
In my reading, I paid close attention to diagrams containing: the S3 pricing model, the database options, the four AWS support plans, the AWS Shared Responsibility model. I feel paying close attention to said diagrams helped me crush the exam. I also made sure to memorize the following concepts from my book: the six advantages of cloud computing, the five Trusted Advisor categories, calculator types, and the differences between CloudWatch and CloudTrail. Once again, doing this served me well on my exam. Memorize these concepts front to back, write them down, stick them up on your wall, make flash cards, and do everything that you can to remember them because there will be many questions about these topics covered in the exam.
Preparing your business for future success starts with switching from on-premises hardware to the cloud for your computing needs. The cloud gives you access to more applications, improves data accessibility, helps your team collaborate more effectively, and provides easier content management. Some people may have reservations about switching to the cloud due to security concerns, but a reliable cloud service provider (CSP) can put your mind at ease and keep your data safe with highly secure cloud services.
Cloud security, also known as cloud computing security, is a collection of security measures designed to protect cloud-based infrastructure, applications, and data. These measures ensure user and device authentication, data and resource access control, and data privacy protection. They also support regulatory data compliance. Cloud security is employed in cloud environments to protect a company's data from distributed denial of service (DDoS) attacks, malware, hackers, and unauthorized user access or use.
One of the biggest advantages of using cloud computing is that you don't need to pay for dedicated hardware. Not having to invest in dedicated hardware helps you initially save a significant amount of moneyand can also help you upgrade your security. CSPs will handle your security needs proactively once you've hired them. This helps you save on costs and reduce the risks associated with having to hire an internal security team to safeguard dedicated hardware.
Cloud computing gives you a centralized location for data and applications, with many endpoints and devices requiring security. Security for cloud computing centrally manages all your applications, devices, and data to ensure everything is protected. The centralized location allows cloud security companies to more easily perform tasks, such as implementing disaster recovery plans, streamlining network event monitoring, and enhancing web filtering.
Cloud computing allows you to scale with new demands, providing more applications and data storage whenever you need it. Cloud security easily scales with your cloud computing services. When your needs change, the centralized nature of cloud security allows you to easily integrate new applications and other features without sacrificing your data's safety. Cloud security can also scale during high traffic periods, providing more security when you upgrade your cloud solution and scaling down when traffic decreases.
Finding the right CSP solution with rigorous security cloud services is essential to your data's protection and your company's overall safety. A good vendor will know the importance of security in cloud computing and have a few main features to lower risk. For example, a vendor with rigorous cloud-based security will have controls designed to prevent data leakage and support data encryption and strong authentication.
A true cloud deployment allows companies to pay a fee in exchange for access to servers and software that they do not have to manage. SaaS ERP solutions are a popular version of a true cloud solution, as the vendor handles everything on the back end including patches and upgrades. True cloud is also known as multi-tenant because multiple businesses use the same software instance and hardware. This reduces the need for an in-house IT team and ensures that the company always has the most up-to-date, secure version of the software.
In addition to the handling of digital evidence, the digital forensics process also involves the examination and interpretation of digital evidence ( analysis phase), and the communication of the findings of the analysis ( reporting phase). During the analysis phase, digital evidence is extracted from the device, data is analysed, and events are reconstructed. Before the analysis of the digital evidence, the digital forensics analyst in the laboratory must be informed of the objectives of the search, and provided with some background knowledge of the case and any other information that was obtained during the investigation that can assist the forensics analyst in this phase (e.g., IP address or MAC addresses). Various forms of analyses are performed depending on the type of digital evidence sought, such as network, file system, application, video, image, and media analysis (i.e., analysis of data on storage device) (Grance, Chevalier, Kent, and Dang, 2005; Carrier, 2005; European Network of Forensic Science Institute, 2015; SWGDE Best Practices for Image Authentication , 2018; SWGDE Best Practices for Image Content Analysis , 2017; SWGDE Guidelines for Forensic Image Analysis , 2017; SWGDE Best Practices for Data Acquisition from Digital Video Recorders , 2018; SWGDE Best Practices for Digital & Multimedia Evidence Video Acquisition from Cloud Storage , 2018). Files are analysed to determine their origin, and when and where the data was created, modified, accessed, downloaded, or uploaded, and the potential connection of these files on storage devices to, for example, remote storage, such as cloud-based storage (Carrier, 2005). The type of digital evidence (e.g., emails, text messages, geolocation, Word processing documents, images, videos, and chat logs) sought depends on the cybercrime case. 2ff7e9595c
