Pros

Cons

  • Reduced risk of network outages: Businesses can have constant network uptime, usually 99.982% with a Tier-III Data Centre, when opting colocation service as colocations have redundant systems in place that make sure the networking is always up, even after unfortunate event of system failure. Colocation vendors also utilize virtualization that offers clients recent system snapshots that may help them recover from nasty system failures.
  • Flexibility to choose software and hardware specification: With colocation arrangement, you have an option to choose hardware and software specification of your business needs. The colocations only offer the essential network infrastructure along with the physical space in form of cabinets or server racks or cage for housing servers. The clients themselves are responsible for buying software and hardware that best meet their business requirements.
  • Affordable: Budget may be the biggest constraint for startups and SMEs. By co-locating their servers in a shared environment, they actually share costs among multi-customer thus saving huge money that would have spent in establishing their own in-house Data Centers. Additionally, it allows them to reap the benefits premium bandwidth at a lower cost and the services of specialized professionals that would not be reasonable for them if running own Data Centers.
  • Maintenance at remotely located 3rd-party Data Center: Since your server is housed in a remotely located third-party Data Center and you are responsible for maintenance yourself, it becomes a time-consuming affair to send your professionals at the Data Centre every time there’s issue arises.
  • Responsibility to manage server: Hardware and deployments are yours so are the responsibility to fix issues whey occur. The onus to fix such issues is on you as you would have been doing in your on premise Data Centre. If you do not have seasoned-geek to solve such issues, you may have a tougher time trying to bring server operation in normal condition, making colocation a big ‘thumb-down’ for you.
  • Huge upfront-cost: Colocation Vietnam is no doubt a great option for businesses that have budget and resource constraints. But it should not be interpreted that colocation does not require upfront costs. As you would be purchasing your requisite software and hardware for colocation, the upfront costs will still be huge.

3. What are the basic difference and similarities between Colocation and Dedicated server?

DEDICATED SERVER

COLOCATION

Dedicated server service meets the demands of expanding hardware to run large websites and store big data. This service is suitable with large enterprises that have strong budget or run short-term projects.

Colocation service meets the demands of locating servers in Tier 3 data centers that ensure high transmission speeds and 24/7 technical support. This service is suitable with enterprises that have stable budget, run long-term project and are capable of self- system administering.

What are the basic differences?

The owner owns the server, the routers and the other hardware and software that are kept in the data center. The role of the colocation vendor is to provide for the electric and power needs to keep the server running, internet access and storage facilities. One of the most basic reasons why businesses chooses colocation data center is that they may have outgrown their available space and the only other solution would be to place it in another location rather than building or retrofitting their present structure that would be very costly.

Dedicated server is a service where the server that is housed in the Data Center as well as the other equipment and software used in the operation of the server is owned by the hosting service vendor. Basically, the customer does not get to own the server but rather only rents it. The hosting vendor provides all the necessary services needed to run the Data Center including maintenance, backup and physical security. Though the company owns the server, the site owner enjoys complete control over the site’s content and build but the company gets to decide when to upgrade the server.

Their basic difference lies in the fact that colocations are owned by the site owner while dedicated hosting servers are fully owned by the hosting company and are only rented by the site owner.

What similarities?

In reality, colocation and dedicated server share a number of similarities which is the reason why people usually confuse colocation with dedicated sever or dedicated hosting with colocation. These similarities are the following:

  • Both Vietnam colocation as well as dedicated server are solely dedicated to your web. That means you don’t have to share its resources with any other user. And two of them are considered to be expensive compared to other hosting solutions however both are also recognized to bring benefits that far outweigh their cost. Dedicated server and colocation are used by large enterprise and webs that value hands-on control, security, privacy, space and the important resources of their servers.
  • Both come with the option to be managed or unmanaged. Managed means that the hosting vendor takes care of everything for you, saves for those that you want to manage yourself whilst unmanaged hosting means that you are responsible for everything in your site.
  • The answer to the question of which is better between colocation and dedicated server is really dependent upon the choice of the site owner. They only differ in the ownership of the servers which puts them at par with each other in terms of performance as owners get to choose the type and specifications of their servers. The main difference is in the price, if you want to escape paying a huge upfront amount yet pay a bigger monthly fee, go for choosing dedicated server. But if you’re willing to take the risk of spending a bigger amount upfront and get to enjoy the fruits later, then colocation is definitely for you.
