What is a public cloud?
A public cloud is the most common mode of cloud service deployment, in which a third-party cloud services provider provides various services via the internet to enterprises and organizations. In other words, a public cloud is where enterprises and users share on-demand computation infrastructures and added services provided by a cloud-services provider.
The physical infrastructures and hardware facilities of the public cloud is managed and maintained by the cloud-service provider. The public cloud services encompass resources like virtual machines, applications, networks and storage, enterprises can opt to adopt one or more public cloud services to complement their own internally deployed private clouds, forming a hybrid cloud; or employing multiple public clouds to form multi-clouds services that can swiftly adapt and satisfy resources such as IaaS, SaaS and PaaS with more abundant and flexible options.
Recommending public cloud: four major advantages
Features of public cloud include can adapt to significant economic scale, flexible expansion, and full automation; it is also more cost-effective and competitive than building an internal data center that were deployed On-Premise.
- Excellent scalability
Expands or reduces the scale of cloud resource usage based on the needs of the users. - Lower capital costs
Users can save major costs on building data center infrastructure and equipment, and also save on the future burden of operational maintenance. - Pay-as-you-use
The public cloud has a pay-as-you-use payment scheme that bills users based on amount of usage and size of storage. It’s a smart payment method to prevent unnecessary costs and also allowing more flexibility to suit any requirement. - High reliability
Since the public cloud is dispersed over several data centers, it has less risk of single-node failure. Using cloud-storage service as example, the reliability of data storage can be ensured by multiple measures such as multiple mirrored and distributed replica backup, remote replication, and snapshots/cloud backups.
Differences between private, hybrid, and public clouds
Aside from public clouds, the following are comparisons between private and hybrid clouds, which are for customers to better understand the differences in cloud services, allowing them to select the most optimal method to achieve digital transformation.
Comparison between private and public cloud
A private cloud is a cloud service utilized internally in an organization. Like normal cloud services, it has advantages like ease of use and good scalability. What makes it different from a public cloud is that it is similar to an On-Premise server rack or a conventional data center, where users will have assumed responsibilities in management and operational maintenance, resulting in higher operational costs.
Advantages of private cloud:
- Data security
With its single-tenant architecture, private cloud is only limited to internal use and outsiders are restricted from accessing its resources. Therefore, it is suitable for financial or government sectors where data security and privacy are highly valued. - Data transmission efficiency
Since the resource supply and demand ends are under the same environment, the low distances allow better transmission efficiency. - Customization
A private cloud is established by the user’s own personnel and often is customized according to the needs of the enterprise. It can also flexibly adapt to any special requirements on the fly.
Comparison between hybrid and public cloud
Hybrid cloud is the combination of a private and public cloud, integrating the both clouds advantages together. For instance, users may exploit the advantages of both private and public clouds, such as using private clouds to process confidential information and public clouds for the rest. Doing so not only has the advantages of high flexibility and computational performance, but also confidentiality and low latency.
Aside from the security and convenience, the advantage of hybrid cloud means that user workloads can distribute between private and public clouds, meaning better usage flexibility and can adapt more swiftly to business development needs. However, a hybrid cloud will have higher costs in system integration and difficulty in resource management than a private or public cloud.
How to choose high-quality cloud service provider
In terms of economic consideration, the three major public platforms in the world – AWS, Microsoft, and GCP – have significant cost competitiveness, due to their global-based market scale. The mode of sale for these platforms is akin to self-service; the users are responsible to manage, monitor, and resolve issues after the services are activated online. Users can only address their technical issues through customer service emails or via dealers, and language/time zone differences make it difficult for issues to be resolved immediately. In some countries, legislation requires enterprises to store confidential data locally in private clouds. Data stored in the public clouds of these global vendors are only represented as regions, and their exact storage locations cannot be determined.
Enterprises wishing to use a public cloud platform must consider the amount of bandwidth available to satisfy the needs for large data backups, as well as the connection of dedicated lines; for net neutrality, the service should also allow flexible switching. Under these premises, the options are relative few and thus only local cloud services could be considered. Some enterprises lack sufficient IT talent and need to rely on the 24/7 manpower support of the cloud service providers, satisfying their needs for technical support and consultation and reducing the costs of enterprise human resources.
Four main advantages creating core values
- A strong and experienced professional technical team
Take eASPNet as an example, the GWS is based on the SDDC technology from VMware, a leading provider of multi-cloud services for all enterprises. Not only is eASPNet a VMware Cloud Verified partner, but its technical team has also acquired hundreds of professional certifications, adding the staff’s rich experiences in data center O&M and IDC services such as hosting and co-location, and stable service quality is always guaranteed.
- Carrier neutrality
eASPNet started as a carrier-neutral data center that allows interconnection between many colocations and interconnection providers. We are not tied to any one service provider (telecommunications, ISP, or other), providing diversity and flexibility for the client seeking service. Whether it is the GWS public cloud, private cloud, GWStack all-in-one machine, or the On-Premise Legacy Server of a corporation, when combined with international public clouds into hybrid clouds, eASPNet is always ready to help.
- Affordable prices
eASPNet provides localized services with 24/7 technical consultation support full-year. Therefore, clients don’t need to seek help from international public cloud distributors or pay extra fees for support. In addition, eASPNet allows interfacing with MPLS VPN, ADSL, or other lines from any telecommunications provider, enabling switching and connecting at all times without generating any hidden costs.
- Submarine cables accessing the world
The Taiwanese government approved the international submarine cables in 2000, and they interfaced with the primary data center through land optical cables after landing. The eASPNet’s data center had already become one of the landing spots, with another two locations at Toucheng and Bali serving as a complete backup submarine cables ecosystem. eASPNet’s data center has become an Internet exchange center, international data circuits, and public cloud provider. As soon as interfaced with optic cable networks from local ISP providers, all types of internet services can be provided to clients or end-users. Therefore, service providers like eASPNet with abundant international resources are the top choices for enterprises conducting international operations, and integrating clouds and global networks.
