As the global demand for cloud computing continues to double, cloud computing is not a whim, but a technology and various applications that have slowly developed from decades of information technology. With the rapid progress of the times and changes in the general environment, the public can enjoy cloud services at any time.
What is the Cloud?
The cloud virtualizes servers to form a virtual resource pool, which saves resource costs and facilitates management compared to previous physical machines. Cloud is the concept of computing, storage, and network resource pooling.
What is Cloud Computing?
With the development of the Internet, cloud services and applications have become more and more complex, requiring support for more users, stronger computing power, and more stability and security. Using traditional methods such as a more complete IT operation and maintenance department will consume a lot of energy and financial resources, and it will still be difficult for large companies to meet the demand. For those small and medium-sized enterprises and even individual entrepreneurs, creating software the cost of product operation and maintenance is even more unbearable. After the emergence of cloud computing, after the application is deployed to the cloud, there is no need to pay attention to hardware and software problems, and they will be solved by the professional team of the cloud service provider. Using shared hardware, if you buy this cloud service according to your needs, you can use the software updates, and the on-demand expansion of resources can be completed automatically.
What are the Basic Characteristics of Cloud Computing?
- On-demand self-service:
Consumers can unilaterally regulate computing power, such as server time, and network storage, and can automatically interact with individual service providers without manual intervention.
- Broad network access:
Computational power can be accessed and obtained over the Internet through standard mechanisms that facilitate the use of customer platforms at different scale levels.
- Resource pooling:
Cloud providers serve consumers through a multi-tenant model. Physical and virtual resources are dynamically assigned or reassigned according to consumer requirements. Under the concept of location independence, consumers usually do not know the exact location of all resources, and can only grasp large-scale regional locations such as countries, states, or data centers. Resources include storage, processing, memory, network bandwidth, and virtual machines.
- Rapid elasticity:
Computing power can be scaled flexibly and quickly according to demand. To the consumer, the size of the functions available for configuration appears to be infinite and any number can be accessed at any time.
- Measured service:
Cloud systems automatically control and optimize resources by utilizing a certain level of abstraction metering capabilities suitable for service types (such as storage, processing, bandwidth, and active user accounts), and can monitor, control, and report resource usage. Both providers and consumers provide transparent service usage information.
What are Cloud Services and Cloud Platforms?
Cloud service mainly combines cloud computing, cloud storage, and network connection to develop various application services on the Internet.
A cloud platform can be understood as a cloud computing service provider that has N multiple servers and storage devices and uses information technology to integrate them into a platform that provides storage services. This platform provides services by leasing. Cloud services generally refer to obtaining required services in an on-demand and easily scalable manner through the network. Cloud services can put the software, hardware, and data required by the enterprise on the network, and use different IT equipment to connect at any time and place to achieve data access, computing, and other purposes.
What is Cloud Storage?
Cloud storage refers to a system that integrates many different types of storage devices in the network through application software to work together to provide data storage and business access functions through cluster applications, grid technology or distributed file systems, and other functions.
Cloud storage is a cloud computing system with data storage and management as the core. A system that integrates many different types of storage devices in the network to work together through application software to provide data storage and business access functions to the outside world. The horizontal expansion of cloud storage devices enables the storage system to have the ability to expand infinitely. It can realize the simultaneous expansion of the controller and the hard disk, and the performance and capacity can be linearly expanded at the same time. Cloud storage can generally be divided into private cloud storage and public cloud storage. Through the cloud storage model, the resources and data of the private network are linked, and these resources and data are placed on the public network shared by the public cloud service provider.
Advantages of Cloud Storage:
- The total cost of ownership:
When using cloud storage, there is no need to purchase hardware, deploy storage, or prepare capital for special cases that may occur one day. You can add or remove capacity as needed, quickly change performance and retention features, and only pay for the storage you use. Based on auditable rules, infrequently accessed data can even be automatically moved to lower-cost options to promote economies of scale.
- Deployment time:
When the development team is ready to perform the work, the infrastructure must not hold them back. With cloud storage, IT can quickly deliver the exact amount of storage it needs when it needs it. This allows IT to focus on solving complex application problems instead of wasting energy managing storage systems.
- Information management:
Centralizing storage in the cloud can create an excellent leverage point for new use cases. By using cloud storage lifecycle management policies, you can perform powerful information management tasks, including automated tiering or locking of data to support compliance requirements.
Types of cloud storage:
- Object Storage:
Applications developed in the cloud often take advantage of the massive scalability and metadata features of object storage. Object storage solutions are ideal for building from scratch modern applications that require scalability and flexibility, and they can also be used to import existing data stores for analysis, backup, or archiving.
- File Storage:
Some applications require access to shared files and require a file system. This type of storage is usually supported by a network-attached storage device (NAS) server. File storage solutions are ideal for use cases such as large content repositories, development environments, media repositories, or user home directories.
- Block Storage:
Other enterprise applications such as databases or ERP systems typically require dedicated, low-latency storage per host. This is similar to Direct Attached Storage (DAS) or Storage Area Network (SAN). Block cloud storage solutions are built with every virtual server and provide the ultra-low latency required for high-performance workloads.
How Secure are Cloud Services?
Many companies remain concerned about the security of cloud computing services, although security breaches are rare. How secure cloud computing is depended largely on how secure your existing systems are. An internal system managed by a team with many other things interfering may be more prone to leaks than a system where the cloud provider's engineers specifically protect that infrastructure.
These data create infinite value, but on the other hand, once a cloud computing platform leaks the user's data privacy, or the data is stored in the cloud due to equipment failure, a large amount of data is lost, or the data is in the process of transmission. It is arbitrarily tampered with by other users, and the consequences of such consequences are incalculable. In the cloud era, information security is still one of the topics that everyone pays attention to.
The Future of Cloud Computing:
Cloud computing currently accounts for a larger share of enterprise technology spending than traditional on-premise delivered applications. However, cloud computing usage is only likely to climb as businesses become more comfortable with the idea of cloud computing. Cloud computing providers are increasingly promoting cloud computing as a medium for digital transformation, rather than simply focusing on its costs. Moving to cloud computing can help companies rethink business processes and accelerate business change by helping to break down data and organizational silos. Some companies that need to facilitate digital transformation may find this statement appealing; others may find that as the cost of switching increases, it is a consideration for company-side operating decisions.
