Unraveling the confusion about PaaS

Overcoming any skepticism about Platform as a Service will require more of an operational focus. As discussed in our last post, there's a lot of "dev" in PaaS, but not enough "ops."

Recently, JP Morgenthal, director of the cloud computing & DevOps practice at Perficient (and a long-time enterprise software thought leader), led a BrightTalk panel discussion on promoting PaaS adoption to skeptical enterprises. He was joined by Ed Anuff, Apigee; Sean Allen, OutSystems; and Sarbjeet Johal of Unified Cloud.

The first challenge is that definitions of PaaS tend to be relatively murky, and often overlap with Infrastructure as a Service. (Even the Wikipedia definition of PaaS is flagged with "multiple issues.")  Helping to kick off the discussion, Allen defined PaaS as "a cloud-based service that integrates and manages all aspects of your application stack.... anything that allows you to build cloud-based applications without worrying about storage or other stack-based components." Johal adds that PaaS is likely to be seen in implementations such as "Hadoop as a service, data crunching as a service or integration as a service."

Expect this uncertainty to continue, even through 2015, which Gartner predicts will be the year of PaaS. "The PaaS market is going to go through a number of stages in relatively rapid succession," Allen predicts. "If you take a look at the commoditization pressure in the IaaS price wars between Google and Amazon Web Services, they’re going to need to differentiate their offering, and they’re going to go upmarket. And to go upmarket, they’re going to have to consume the bottom end of the PaaS market."

This blurring between IaaS and PaaS will likely continue for some time to come, Allen continues. "The distinction between a PaaS like a Heroku and what you get from Amazon is by necessity is going to converge. You’re going to see a lot of specific use-case PaaSes to continue. Things like Docker are already causing a lot of disruption in both the IaaS space and PaaS space, and I think it’s going to continue to have some impact as well."

Expect to see considerable pressure -- and movement -- to opening up more aspects of PaaS to the operations side of IT. "To promote the production side, developers and operations folks have to sit together -- we call it DevOps these days," Johal states. Operations people "have to see the clear benefit. That will come through education, and doing a pilot of a simple application -- a two-tier application that is simpler in nature -- and try that and deploy that and see the advantages of that."

The way to promote PaaS is to "convince and show the operations people that this new way of doing it provides significant value that’s not matched by increased risk," Allen agrees. "Take a look at risk-rewards scenario, and show them the value of their sleepless nights being minimized with a transition to a new approach."

The solution sets are not ready yet, however. "Right now that the way that it is it’s not really DevOps in a box yet," says Anuff. "It's hammers and nails and wrenches in a box that help you create DevOps practices to a degree. The biggest obstacles are stovepipes. PaaS can play a very significant role there."

Panelists agree that the PaaS market will be going through a broad spectrum of adoption. "There need to be some more consistency around one particular platform to give you some confidence where to invest," says Morgenthal. "In 2015, it’s going to be slow growth. I haven’t heard anybody say PaaS is dead on arrival, or that PaaS is dead, long live PaaS. That’s a good sign. It’s still climbing a hill, and we’ll see where it grows."

Japan volcano: Mt Ontake rescue teams find 31 bodies

The bodies of 31 hikers have been found near the top of Japan's Mount Ontake a day after a sudden volcanic eruption.

The hikers were not breathing and their hearts had stopped. The search for a total of 45 missing climbers has now been called off for the night.

The volcano, about 200km (125 miles) west of Tokyo, erupted without warning on Saturday, spewing ash and rocks.

About 250 people were trapped on the slopes of the popular beauty spot, but most got down safely.

Japan is one of the world's most seismically active nations - but there have been no fatalities from volcanic eruptions since 1991, when 43 people died at Mount Unzen in the south-west.

First deaths confirmed
Saturday's eruption forced many of those on the mountain to make emergency descents through clouds of volcanic ash and falling rocks.

"The volcanic rocks fell like hailstones," one man said.
"We couldn't breathe so we covered our mouths with towels. We couldn't open our eyes either."

Another told reporters: "The volcanic ash was hurtling so fast I couldn't run away. I'm worried about people still on the mountain."

Almost 50 people were thought to have stayed on the mountain on Saturday night, reports said.

Rescue efforts will resume on Monday after an intense search on Sunday was called off because of toxic volcanic gases in the area.

It is understood 45 people are still listed as unaccounted for - including those found near the summit. There are fears that others could be buried under volcanic ash.

Four people were transported back down the mountain on Sunday and later confirmed dead, Japan's NHK News reported.

Japanese officials can only announce deaths after a formal doctor's examination.

Analysis: Rupert Wingfield-Hayes, BBC News, Tokyo
The question many people have been asking is - why were there hundreds of people on top of an active volcano? And, why was there no warning it was about to erupt?

The answer to the first question is that there are lots of active volcanos in Japan, and people hike on them all the time. I have done so myself. Mount Fuji is classed as an active volcano, and hundreds of thousands of people climb it every year.

In some ways the people caught in Saturday's eruption were very unlucky. It was a beautiful sunny Saturday at the peak of the autumn hiking season. Had it been a rainy Wednesday in June the chances are very few people would have been up there.

The question of no warning is harder to answer. Volcanologists point out this was a relatively small eruption, and that it was driven by super-heated steam and ash, not by lava being ejected from the magma chamber. That made it much more difficult to predict.

But it also meant that many of those caught up in the eruption survived. Had it been a large-scale eruption (like the one in 1979) with large pyroclastic flows, many more would have been killed.

Tips for a Healthy Pregnancy

Pregnancy is something that can make a mother feel happy. Keeping the baby in the womb to grow healthy and born alive is to be performed by a pregnant woman. The gestation period will determine the child's growth. Here we provide some tips on healthy during pregnancy.

Folic Acid and Zinc
Healthy foods for pregnant mothers are foods that contain folic acid and zinc. Folic acid is useful for preventing neural tube defects in infants and spine. Foods that contain folic acid present in cereals, brown rice, oranges, green vegetables, beans, broccoli, and more. Zinc is useful to prevent anemia during pregnancy. Anemia is very dangerous for pregnant women, can cause bleeding during childbirth.

Avoid Cigarette Smoke
Cigarette and tobacco smoke are very harmful to the health of mother and fetus. Avoid cigarette smoke; try not to become passive smokers. If your husband is a smoker, warn not to smoke near you. And if you're also a smoker, stop smoking better. Cigarette smoke will make your baby born weighing less, easily hurt, slow growth; it can even cause miscarriage and death in the womb.

Drinking Adequate Water
Drinking adequate water is another important thing to note for pregnant women. Drinking lots of water is very useful for pregnant women, because the incoming fluid will help to increase the blood volume that occurs during pregnancy. Drink at least 6-8 glasses a day, can be fruit juice, milk, or water.

Taking Medications Safely
Be careful when taking some drugs. If you are attacked by a disease or pain, be careful taking drugs. You should immediately consult your physician before taking it. If you are pregnant and taking medication without rules would be harmful to the fetus in the womb.

Taking a pregnancy exercise classes are also good, in addition to the benefits to the mother and fetus, the pregnant women in the class are able to share experiences and gain knowledge. In between activities, do not forget to rest

Vaccination During Pregnancy
Another important thing is vaccinated during pregnancy. Pregnant women should talk to their physicians to figure out which vaccines they might need and whether they should get them during pregnancy or wait until after their child is born. Hepatitis B, Influenza and Tetanus/Diphtheria are considered safe to give to women who might be at risk of infection.

Nurse-Physician Collaboration

To achieve effective service the nurses, physician and healthcare team should collaborate with each other. No one group can claim more power over others. Each profession has different character so that when combined can be a force for achieving the desired goals. 

Nurse Physician Workplace Collaboration
With good communication and respect for other professions in shared decision-making (in collaboration) in the group it will create a good work team so committed to providing a comprehensive service can be created. Opinion between physician and nurses need to be a standard domain with (physician-nurse) standard.
There are significant differences in the collaboration between groups of patients with severe, moderate, and independent. Practice negotiating collaboration on many stages in patients partially dependent (being) because of the patient's full dependence (severe) physicians only give direction and decisions without consulting nurse.

Of the need for education and socialization practices of collaboration among work teams managed care health or health professions ranging from education situation. For hospitals need to improve the quality of nursing care health. An increase in nurse education and good communication between team and patient to work, and to improve the practice of collaboration needs to be a shared commitment between leaders (structural) and functional (health professions), where the principal can adopt managed care and socializing and can be applied to services.

How to Teach 1st Grade

Teaching 1st grade will be different by teaching high school students. Required certain techniques so that the child can absorb lessons more fun considering the psychological child is still in the early learning stages.

The voice sounded clear enough by children, intonation, etc. are things that are very important to be possessed by the teacher. For early elementary grades, they are still considered early childhood, before providing early childhood learning, as teachers need to recognize the characteristics of elementary school age children first. Do not forget to always give something new and varied for them. No need expensive, objects in the environment can be the object of exploration for children.

The period is also very short of their concentration. Thus, teachers must have a second plan, and even third, fourth plan needs to be prepared for them so they do not saturate. Keep in mind that early childhood is a period play. Thus, the instruction given to them should be based on the principles of play (fun, children can explore, gain a lot of experience).

Children are not miniature adults but they have the characteristics and uniqueness of each. So, do not equate them with the high school kids that are easier on the set and was able to concentrate for a long time.


Self-confidence is one aspect of personality that is very important in human life. Self confident people are confident about their own abilities and have realistic expectations, even when their expectations are not realized; they stayed positive and can take it.

Self-confidence is a mental or psychological condition of a person who gives a strong confidence in him to do or perform any act.

People who have good self-confidence are not the only person who feels capable of (but not really afford) but is a person who knows that he can be caused by experience and calculation that he did.
Synonyms:  aplomb, inner strength, positive self-image, self-assurance

Personality traits of people with low self-confidence
When this is linked to the practice of everyday life, people who have low self-confidence or have lost confidence, tend to feel / be as below:

Help: low self-confindence
Counselling,  life coaching, and hypnotherapy are common therapies used to help improve self-confidence.

Acyclovir Pharmacology and Indication

Acyclovir is acyclic purine nucleoside analogue active against herpes simplex virus, varicella zoster, Epstein-Barr virus and cytomegalovirus. In the cell, undergo phosphorylation acyclovir acyclovir triphosphate into an active form that inhibit the herpes simplex virus DNA polymerase and viral DNA replication, thereby preventing viral DNA synthesis without affecting normal cell processes.

Acyclovir Pharmacology
Acyclovir is an antiviral agent highly active in vitro against herpes simplex virus (HSV) types I and II, and varicella zoster virus. Upon entry into the infected cell, the phosphorylated form of the active compound Acyclovir Acyclovir trifosfate. The initial phase of the process depends on the enzyme thymidine kinase viral-coded. Acyclovir trifosfate act as inhibitors and as a false substrate for the herpes-specified DNA polymerase which prevents viral DNA synthesis without affecting normal cellular processes.

Treatment of herpes simplex virus infections of the skin and mucous membranes including initial and recurrent genital herpes / recurrent, herpes zoster (shingles / shingles / shingles). Preventing recurrence of herpes simplex infections in patients with strong immune systems. Preventing herpes simplex infection in patients with poor immune systems.

Another acyclovir pharmacology is a treatment of herpes simplex virus infections of the skin and mucous membranes including initial and recurrent genital herpes / recurrent, herpes zoster (shingles / shingles / shingles); preventing recurrence of herpes simplex infections in patients with strong immune systems; preventing herpes simplex infection in patients with poor immune systems.

Acyclovir Indication
Acyclovir indication such as treatment of herpes simplex virus on the skin and mucus membranes, including initial and recurrent genital herpes; treatment of herpes zoster and varicella infections; treatment of infections caused by the herpes simplex of the skin and mucous membranes including initial and recurrent genital herpes, herpes simplex infection prevention in immuno-compromised patients; treatment of herpes zoster infection.

5 Tips In Finding Hotel

You are planning a holiday abroad for your family, and want everyone to have a good time. You surf the internet for hotel descriptions, but from the pictures you see and what you read, all hotels project a perfect image of themselves. How can you know which one is better? You have never been there and knows nothing of your destination. At the same time, you do not want a hotel room to spend your budget. How do you choose?

Check Independent Hotel Rating
Well, the first step you can take is to visit the hotel to see the search engine ratings from previous visitors. In order assessments for every hotel, most agents ask for an assessment of previous guests. Reading their comments will give you a fair idea of ​​what to expect from the hotel which is located in your destination. Make sure to read some of the comments in order to get a fair picture. Certain incidents described only a rare occurrence that may have been corrected.

Hotel Chains and Facilities
Are they part of an international hotel chain? Most international chains have strict standards attached and the default theme in all of the chain. They may have the same amenities (health club, spa, business center, etc.) are essential to maintain a high standard of hotel. Other things you can look out for shuttle services including concierge, to the city, airport transfers and laundry service is good.

Perhaps one of the most important things when choosing a hotel is the location. Hotels close to shopping center, train station or city center level higher charge than those located elsewhere. Analyzing maps of the area before you order to determine the nearest shopping center or access to the train station that will provide you with a lot of ease in moving around. Also, check with the hotel if they have a large tour groups arrive at the same time. Hotel costs are higher during periods of high occupancy, and do not have the flexibility of late check-out. This is an important aspect that, if ignored, can affect your tour itinerary and your impression of the level of hotel hospitality.

Prices and Discounts
The hotel rates are a huge factor when it comes to choosing a hotel. However, paying more does not always mean that you will receive an equivalent level of service and standards. One way to maximize the price will check if they are part of an alliance with airlines or car rental companies, offering customers a discount for their allies. Sometimes, credit card companies offer their cardholders exclusive rate for special which can be very interesting. In addition, if it is possible to use your frequent flyer points to redeem hotel discounts, this could help reduce the cost of the hotel as well.

Boutique Hotel
Finally, apart from chain hotels, boutique hotels may be a good alternative for a romantic place for couples or families looking for a more typical of the theme. Many boutique hotels have less space but offer value added services such as in-room spa bed, breakfast in bed or even in-room massages. In the end, your choice of hotel really depends on what you want from your holiday.
