Avoid Excessive Server Consolidation

February 15th, 2014 Comments off

The term “server consolidation” has frequented the top of the agenda of those who are responsible for IT in organizations. To reduce the number of servers follow the desired reduction in energy costs and lower resource requirements for refrigeration equipment, besides the obvious space savings.

It is understandable that the wave of consolidation has arrived in full force in IT departments and their success has been contagious. The tactic is adopted across the IT industry, large and medium enterprises. Even small structures have been streamlined to the limit.

The trend is followed by providers that now offer solutions that match that philosophy. All this euphoria hides a fundamental fact: the mass adoption of such technology will result in weaker systems and severe risks.

The more bodies rotate on a dedicated server, the worse will be the consequences of possible outages.

Systems configured virtualization followed a traditional architecture that have stopped services in certain cases of falling services. It can be a mail server, or application. Of course all the associated machinery will feel the effects of unavailability still be somewhat limited.

In the case of server consolidation this picture changes and range of risks is inflated and with worse consequences for small businesses that have a greater number of applications running on the server.

In times of virtualization processes and transactions, such unavailability is dreaded by IT and abhorred by the management of the business.

IPv6, A Technical Challenge For The Internet

February 12th, 2014 Comments off

ipv6-challenge The Internet has become a fundamental part of society. Everything indicates that is here to stay and that each day will depend most. It is likely a future where the network and the computers will be invisible. They will be so integrated into our daily lives, disguised in everyday objects that we will not think about them anymore, simply will use them. In actuality, however, the network faces a series of challenges that must overcome to keep evolving and even existing.

One of the main challenges of today’s Internet, however, is still known by few. It involves a radical change in its most basic technology: changing the IP protocol.

A “protocol” is just a set of rules to computers and other devices can communicate. IP, or Internet Protocol, is basically two things. He identifies each device on the network with a globally unique numerical address. Also divides the information into small pieces, called packets, and mark with the source addresses and destination. Each of the applications on the Internet: email , web , video and audio conferencing, chat , exchange files, all the same, depends on IP. This protocol is the key to the Internet work in many different media and telecommunications key person to make a more intelligent use of them than traditional technologies such as telephone and TV. The IP is really the heart of the Internet. That is why this issue is important.

This challenge is the fact that the number of addresses is limited. Free addresses will soon be exhausted. In India, even in 2014. There will be a blackout on the Internet. Everything now works as a general rule, keep working. The question is really how to support growth, as new users and devices connect after that.

We have only about 40% of the population with access to the network. There is also a tendency for many types of devices are also connected. For example, in addition to computers, tablets and smartphones , it is common to find games and connected TVs. The demand for growth will only increase. The shortage of addresses in use in version of the IP protocol, IP version 4, or IPv4, has been predicted for many years. A new protocol, IP version 6, or IPv6, is designed to replace it. Change is complex and is delayed. Although similar, the protocols are incompatible. This requires a period of coexistence, with both operating simultaneously.

ISPs will soon deliver IPv6 addresses to their customers. There are many trusted web services and already operating with IPv4 and IPv6 simultaneously as Google , Youtube , Gmail , Facebook , Yahoo , Netflix and thousands of others. However, most banks, governments and ecommerce still do not work well. Where were met only with new technology by providers, users will not be able to access the part of the Internet that still uses legacy technology. Therefore providers also deliver an IPv4 address for each client.

But how, if there is more? They use a similar technique that is used in business today, to share addresses: the CGNAT or Carrier Grade NAT. A user share the address legacy with dozens of other users simultaneously. This works, but brings a number of unwanted side effects. One of the more negative is the more difficult, sometimes impossible, to identify the author of a crime, fraud, or any other kind of evil done online. The technique can also cause malfunction or slowness in some websites and services, especially streaming audio and video, games and file sharing.

A company that has a website today if you do not deploy the new technology quickly, run the risk of seeing their service unavailable, or not working very well for a growing number of users.

The deployment of IPv6 in enterprise networks can be done in a gradual and planned manner, yet, but deployment services accessed via the Internet by external users, this is an emergency! A big problem is that some telecom operators, as well as some web hosting companies in India are delayed and not yet offer IPv6 for the enterprise market. In many cases, it is necessary to switch suppliers. The new technology also requires support in equipment.

In infrastructure networks, devices have IPv6 support for several years. Computers and tablets in general, are also prepared. There is a problem, however, with smartphones. Many models still sold in stores do not support. The same is true for smart TVs, gaming consoles and other gadgets . Consumers buying these equipment attached to the legacy protocol today, may have problems in the not too distant future.

There is some confusion about the timing correct this change, generated mainly because there is no “dates from the turn.” However, more delayed or not a failure can be catastrophic to the Internet.

Dear reader, if you are an entrepreneur, or responsible for an IT company, make sure that IPv6 is enabled on your website , email and other services accessed externally ASAP. If you are just a user of the Internet, pay attention to purchase equipment and services, such as routers wifi , smartphones , game consoles, smart TVs, tablets , internet access, etc.. Know. Already supports IPv6? Only buy or hire if so, or if there is a roadmap clear to resolve the matter quickly. Stay tuned.

How Do You Limit Your Web Hosting Plans?

February 3rd, 2014 Comments off

Some time I have felt the need to update the plans that I offer to my clients. The reality today is that we live in a market that offers unlimited web hosting plans or plans with dozens gigabytes of space.

Some offer only one plan, others offer 3 or 5. There are still those who has nearly 10 plans for a service. And there? Which model to choose?

Personally, I’m a fan of single plane model. It is a statement such as “we have everything anyone needs right here on this plan”. The plan offers 100 gigs of space, 1 tera bandwidth is optimized for WordPress. Who needs more than that to hosting.

They know who needs greatest plans under a vps hosting or dedicated server hosting.

Advantage: Only one setting applies to all users.
Disadvantage: No upgrade. The client will die paying the monthly fee. By chance, the provider offers some additional features like extra database.

Build your plan

It’s what draws the most attention of customers the possibility to have exactly what you need at the price that you can afford. If you need more database, for example. There is an addon for WHMCS for this, but it requires root access to the server, then it is impossible if you are selling or do not have the password.

Advantage: Customized plan and greater flexibility for customers.
Disadvantage: It is what gives more headache that require some extra settings and require more attention at the time of the upgrades.

Several plans

I read a study in Social Triggers that you should give options to the customers, but not many. Apparently, 3 or 4 planes is ideal. More than that and the client does not know which one to choose.

Should be well thought out and properly configured. Most plans are limited by space or number of domains / emails / technology. For example, who offers unlimited plans that can limit per domain.

Advantage: Standard model, easy to follow and execute. Customers are already used to it.
Disadvantage: No. It is widely used in various sectors of trade successfully.

I’ve been thinking of having a single plan, but with less space. Something like 10 gigs. Who needed more, buy a “kit”. A kit would be something like a package with:

  • 01 GB of space
  • 50 GB Bandwidth
  • 01 Database
  • 01 Email account
  • 01 Additional domain
  • 01 Parked domain, etc..

Thus, if the client needs 15 GB of space, it would need to sign the master plan and then add 5 kits.

Advantage: It is interesting, inspirational plans demand of clouds.
Disadvantage: It has been difficult to implement, open ticket in whmcs few days ago and have not received an answer.

Anyway, there are several hosting models and the way you configure your can facilitate or derail your life.

What model do you use?
