In this article, we will do a detailed comparison between cloud servers and dedicated servers. Let’s get started!
Cloud Servers
Performance
In the cloud, multiple servers are combined into clusters using specialized software. Typically, two types of clusters are present: a computing cluster and a storage cluster, both interconnected within the same network. This approach enables the rapid creation of virtual servers with parameters surpassing those of a dedicated server.
Consequently, performance is not restricted by a single server’s computing power, but rather by the collective computing power of the entire cluster. A similar principle applies to the disk system. It’s essential to recognize that the client does not operate alone on the cluster; computing resources are shared among multiple users while maintaining isolation, similar to VDS.
Scaling
Regarding scaling, cloud services offer the simplest and most versatile options. Users can increase the specifications of individual virtual machines (vertical scaling) or scale by adding more virtual machines (horizontal scaling). Additionally, all virtual servers reside in the same high-speed local network, and users have the freedom to configure data transfer rules between servers. For instance, they can implement a load balancer or transfer an IP address from one server to another.
Fault tolerance
Fault tolerance stands as a hallmark of cloud services. Data is redundantly stored across multiple locations, often utilizing external storage solutions.
Moreover, virtual machines are frequently deployed on various servers within a cluster. In the event of one or more server failures, the cloud’s robust fault tolerance mechanisms ensure seamless continuity of operations.
Order time
Cloud solutions offer unmatched flexibility, including in payment terms. Users can choose a minimum order time of as little as 1 hour, and billing is solely based on the actual resources consumed during that time.
What is it for?
The cloud is ideally suited for hosting projects with complex distributed architectures, as well as medium to high-load applications that require rapid and on-demand scaling. Its applications include:
- Medium to high-traffic websites and online stores
- Collaboration services like instant messengers, mail, and CRM
- Storage and processing of large datasets
- Deployment of custom services and bots
- Hosting test and build environments
Dedicated Servers
Performance
The performance of a dedicated server is directly influenced by the chosen equipment’s characteristics, including processor clock speed, memory type, frequency, and disk type. A higher clock speed processor, such as a 5.3 GHz one, will outperform a 2.4 GHz processor. Similarly, NVMe drives offer faster performance compared to traditional HDDs.
The dedicated server’s advantage lies in having all components, both computing and disk systems, on the same motherboard. This setup enables data transfer between components over high-speed buses, ensuring optimal performance. Moreover, you have the freedom to choose the processor, RAM, and disk according to your specific needs and tasks, thereby maximizing the equipment’s potential since you are the sole user.
Fault Tolerance
Regarding fault tolerance, modern servers typically come with dual power supplies and multiple power lines. Clients are advised to use disks in pairs and form a RAID array, such as RAID 1 or RAID 10, for data redundancy. In the event of disk failure, the data remains safe, and the server continues operating without any downtime.
Consequently, dedicated servers are among the most resilient hosting services. Any availability issues usually stem from problems with the data center’s network equipment.
Scaling
Scaling capabilities depend on the server’s ability to accommodate additional equipment. Before renting a dedicated server, it’s essential to know the maximum number of disks, available RAM, and the possibility of replacing the processor to anticipate future upgrades. Expanding RAM or adding disks typically requires 30 minutes or more, as it involves turning off the server, dismantling it from the rack, replacing components, and reassembling everything.
Order period
The order period for a dedicated server usually ranges from a minimum of one month to a maximum of one year. Some providers may have an installation fee, charged at the beginning of service usage. However, we do not have an installation payment for our dedicated server orders.
What is it for?
Dedicated servers are particularly well-suited for hosting projects that demand high processor and disk performance, as well as those with complex architectures that involve combining multiple servers. They are ideal for:
- High-traffic websites
- Storage and processing of large datasets (often more cost-effective than cloud storage)
- Computational tasks, including distributed calculations
- Video conferencing services
- Virtualization systems and orchestration
- Hosting test and build environments
- CRM systems, personnel management, accounting, and business programs designed for large databases and user bases.
