Comparison between Skype free and business version

Introduction

I did some research on “Skype for Business” and compared it against “Skype free version”.  To summarize, “Skype free version” is great for small group of users. “Skype free version” is free to use (good to support up to 25 users in small organization), unless you want to buy credit to make calls to landlines and mobiles. On the other hands, there are three main benefits to use ”Skype for Business” as compare to “Skype free version”:

  1. It is better integration with Office 365  (referring to appendix 1 for detail)
  2. It has security control over your company’s communications (referring to appendix 2 for detail)
  3. It can be used to hold large meetings (up to 250 people).  (referring to appendix 3 for detail)

“Skype for Business” lets clients add up to 250 people to online meetings, provides enterprise-grade security, allows to manage employee accounts, and is integrated into Office apps. Its usage is no additional cost for “Office 365 Business Premium”.

Appendix 1.  You Can Use “Skype for Business” with Office Apps

One of the big advantages of Skype for Business is that it integrates well with Office 365. Skype for Business allows you to send Instant Messages or start a voice or video call directly from a Word or PowerPoint document. You can schedule meetings from within Outlook, present documents, share your screen and even grant permission for someone else to control your desktop remotely. Skype for Business is sold with Office 365 plans for small business, such as our Office 365 Business Premium.

Appendix 2.  “Skype for Business” Has Added Security Features

Skype for Business is designed for companies, not consumers. An administrator can assign Skype permissions. For example, this version of Skype could decide that only salespeople could use it to make international calls instead of leaving the option wide open to the entire staff. The administrator can also deny access to a person who leaves the company to work somewhere else. This allows the company to maintain control over its confidential documents and communications.

Appendix 3.  “Skype for Business” is Better for Large Meetings

 If you’ve used the consumer version of Skype for business meetings, you’ve probably noticed that you can’t have more than 25 people on a conference call. That’s fine if you’re running a small meeting. But, try getting 100 people together for a company-wide webinar and it’s a different story. When you use Skype for Business, you can invite up to 250 people to a meeting. This means it’s a lot easier for you to conduct large-scale presentations or big conferences. And your participants don’t have to be on Skype for Business to participate. All they need is an internet connection and a browser.

Appendix 4. More featured on “Skype for Business”

If you have already purchased the Office 365 Business Premium plan, here are the add-on licenses to get more Skype for Business features.

Recommend Computer Room Temperature

What temperature is right?

tempatureGeneral recommendations suggest that you should not go below 10°C (50°F) or above 28°C (82°F). Although this seems a wide range these are the extremes and it is far more common to keep the ambient temperature around 20-21°C (68-71°F). For a variety of reasons this can sometimes be a tall order.

How do you maintain the right temperature?

Purpose built server rooms are well insulated for fire precaution reasons and air conditioning is essential. In many companies however the maintenance of the air conditioning is separate from the running of the servers. If the air conditioning fails you might not be the first to know. You may even be the last.

Even if everything is working the temperature may fluctuate during the day, from season to season, and there is always the possibility of localized hot-spots around equipment giving off lots of heat.

Don’t be tempted to think that just because you have an air conditioning unit that is up to the job that you are safe. People working in the server room sometimes switch the air conditioning off and forget to turn it on again. Sometimes they leave doors open. Servers run hotter at some times of the day than at others, air conditioning systems sometimes run at lower power at night etc.

What if it’s night time, your air conditioning is running at low power, and your webserver suddenly starts to work hard because the west coast has woken up? Now your machine heats up and your air conditioning can’t cool it enough. Exactly this scenario has been know to happen. Many intermittent faults and slow downs can be traced to overheating.

Replacing old equipment can introduce a new set of problems. Newer machines run faster and often run hotter as well, increasing the burden on the air conditioning systems even more. If you’ve recently introduced new servers or modern switches, it might be time to examining your air conditioning unit to make sure it can still keep up.

Another thing to look out for is the scenario where you turn up the air conditioning unit during the day, in order to ensure the right environment in your server room, but then don’t switch it down during the night or weekends. During the day there might be a lot of activity into and out of the server room. The server room door being opened all of the time lets warmer air into the server room thus necessitating the air conditioning system to be turned up high. At night and at the weekend, without the same level of activity, you may be running up large energy bills for no reason.

How are you going to monitor the temperature?

You need to monitor the temperature in your server room all of the time, especially at night and weekends when nobody is around. A number of systems are available for this purpose, the Temperature Monitor range from OPENXTRA offer good products at reasonable prices. You need to measure temperatures at different points in the room to get an idea of where the hot spots might be. You need temperature measurement to be automated and reliable, so a network attached device is ideal. The device must support alarms, via a number of different methods like email or SMS. You should be able to set the system up and then be alerted when something is wrong.

Section 2. Investigation (分析)

The problem is that those reputed network computer declared our email domain server is spam and blacklist us. We found from the http://mxtoolbox.com, and it will come up the blacklist result which we require to apply for removing blacklist item one by one. However, Weexperience that those blacklist is very difficult to be completely removed. The actual situation is that we cannot guarantee our network without any spam and virus especially difficult for small SME without much investment on network security.

Even-though I submitted for removal, the result was that some were removed, but some others added, as below diagram.Maybe a period of time after removal, it put thedomain to blacklist again.It is a very annoying problem, and quite trouble.
