Arsitektur ManageEngine Mobile Device Manager Plus

ManageEngine Mobile Device Manager Plus supports managing your Mobile Devices from a central point. It allows you to perform Policy Management, Profile Management, Asset Management, App Management and Security Management of mobile devices.
Mobile Device Manager Plus Architecture
Figure 1: MDM Architecture of Mobile Device Manager Plus
*Forwarding Server (optional)


The advantages of using the MDM architecture of Mobile Device Manager Plus include the following:
  • Agentless, Over-the-Air (OTA) Management
  • Uses Apple's Push Notification Service/ Android GcM for communication
  • Profiles and Policies gets deployed immediately
  • All communications to and from the mobile device is secured.


  1. Any communication from Mobile Device Manager Plus to the device is routed through Apple Push Notification service (APNs) via TCP port 2195 for iOS devices and through GCM via TCP port 80 for Android Devices
  2. As per Apple IOS MDM protocol, all iOS devices maintain a dedicated TCP connection with APNs at TCP Port 5223. Mobile Device Manager Plus leverages this to wake up a device using APNs.
  3. Device communicates with Mobile Device Manager Plus Server for available instructions at port 8383 using a secured connection.
  4. Executes the instructions and reports back to Mobile Device Manager Plus Server with the status/data at port 9383 securely.
For the above setup to work, the following should be done
  • Assuming users' mobility, Mobile Device Manager Plus Server should be reachable via public IP address. You should NAT your internal IP of Mobile Device Manager Plus Server to a public IP to enable this. If all the devices managed are within the LAN, this requirement is not needed.

Ports Details

Mengapa sebaiknya bis-bis kita dilengkapi CCTV

Siapa yang tidak kenal dengan CCTV saat ini ? Hampir di semua perkantoran, toko hingga sekolah bahkan rumah menggunakan CCTV untuk memonitor keamanan. Tapi yang saya jumpai di Taiwan ini berbeda. CCTV bahkan dipasang dalam bis-bis mereka.

Mengapa ? Dengan adanya CCTV dalam bis mereka, maka dapat dengan mudah, sang supir memonitor keadaan di sekitar kendaraan mereka. Kalau kita lihat di gambar, mulai dari kondisi di depan supir , belakang bis, samping, dan dalam bis semuanya dimonitor dengan baik.
Kamera CCTV di depan supir memudahkan supir melihat obyek yang mungkin tidak tampak karena tingginya bis. Seringkali ada orang melintas di depan bis tapi tidak diketahui oleh supir. Demikian juga dengan belakang bis. Semua ini akan memudahkan pihak keamanan untuk menganalisa data rekaman yang ada sehingga apabila ada pelanggaran terkait bis ini, maka data rekaman ini bisa digunakan.
Demikian juga dengan kondisi di dalam bis kota. Semua bisa direkam dengan baik, dan semuanya terhubung ke perangkat perekam (DVR) yang dipasang di dalam bis. Untuk keamanan, maka DVR tidak dengan mudah diakses orang sembarangan, dan hanya pengelola bis yang bisa mengakses fisik dan data rekaman.
Semua ini diperlukan untuk menjaga keamanan bersama, baik supir, dan pengguna jasa angkutan yang naik ke bis ini.
Nah semua ini bisa dipasang juga sebenarnya di Indonesia, cuma saya lihat masih dalam batasan terbatas. Kebanyakan bis layanan premium. Selama belum ada aturan yang mengharuskan ini ada, maka tentu tidak akan dipasang di bis-bis kita.

Semua fasilitas dan teknologi ini bisa dijumpai di anggota Asosiasi Sistem Integrator dan Sekuriti Indonesia (ASISINDO) yang tersebar di banyak daerah. Kami siap membantu implementasi dan keamanan CCTV , mulai dari di rumah, perkantoran, bahkan hingga bis seperti ini. Semua ini akan semakin membuat kota kita semakin aman dan nyaman.

Modular data center market to triple its size by 2020

The worldwide market for modular data centers and related equipment is set to grow from $8.37 billion in 2015 to $35.11 billion by 2020.
According to research agency Markets and Markets, North America is expected to remain the largest modular data center market in terms of size, while Asia-Pacific (APAC) is expected to emerge as a high-growth market.

Modular bonanza

Modular data centers consist of pre-fabricated building blocks that can be deployed in a fraction of the time it takes to erect a bricks-and-mortar facility. They include all the necessary IT, power, cooling, fire protection and access control elements.
The modular approach can help grow an existing data center in small increments, while maintaining optimum utilization. Modules can also be easily shipped to areas where building a permanent data center is impractical. They can withstand any weather conditions - modular data centers have been popping up in deserts, jungles and beyond the Arctic Circle - and are perfect for emergency response operations.
The small size and portable nature of such data centers also makes them suitable for mobile network providers, who are increasingly turning to distributed data centers as the platform to run network function virtualization (NFV).
The modular data center market is expected to grow significantly over the next five years, reaching $35.11 billion by 2020, as more hyperscale operators discover the benefits of this approach. This figure includes both complete containerized data center solutions and individual modules designed to provide IT, power and cooling for such environments.
Existing vendors of modular kit include Dell, Cisco, HP, IBM, Schneider Electric, SGI, Emerson Network Power, Flexenclosure, Baselayer and Huawei.
Last month at the Huawei Networking Congress in Beijing, Leon He, president of the Enterprise group for Western Europe, said he believed that cloud and analytics applications of the future would reside in modular data centers.
“At the very beginning, there was the centralized data center. Then, we’ve had the distributed data center, and now there are modular data centers. I think this is a very natural evolution of the data center solution,” he said.
Developing markets such as China, India, and Brazil are expected to lead the speedy growth of the modular market. The report notes that this trend will present plenty of opportunities for various data center infrastructure vendors, and providers of related services.

Modular & Containerized Data Centers

Key Points
- There are many different approaches to modular data centers, from single modules to full data centers in a container.
- Any situation that requires a remote and/or temporary, fully enclosed facility is a potential fit for modular or containerized data centers.
- Containerized data centers are great for edge use cases where resources are needed closer to customer locations.
- Modular may not help with consolidation or the cloud, but it will still find a place in the overall market.

Modular is a major buzzword in the technology world today because everyone wants to believe that the equipment and devices they buy have an assured future. The idea is being used in the smartphone industry now as many vendors are trying to build phones that are more easily upgraded through the use of interchangeable parts and modules. And data center designers are applying the same concept to building data centers with the hope that it will be easier to upgrade them with plug-and-play infrastructure as more or fewer resources are needed.

However, when it comes to modular data centers, the basic modular design concept isn’t the only game in town. In fact, quite a few vendors, including IBM, Flexenclosure, Schneider Electric, Dell, Emerson, BladeRoom, and Baselayer Technology, just to name a few, offer what are considered modular, containerized data centers. These providers essentially build and deliver prefabricated data center structures that are approximately the same size as shipping containers—but can vary through customization—packed with physical infrastructure and essentially serve as portable data center facilities.

Liz Cruz, Associate Director, IHS Markit

“I think there’s positive growth, but I just think a good thing to think about is what portion of the IT load will containerized data centers account for five or 10 years from now? . . . [By] 2020, I have it forecast to be 2.3% of the install base. My forecasts don’t go out further than that, but I wouldn’t say it’s ever going to be more than 5%. After this many years, in a time when the initial investment is so important, it’s still more expensive than a traditional build. No supplier in good conscience can tell me that it’s ever going to get less or even competitively priced with a traditional build. That’s a big factor. If it’s more expensive, then it’s always going to be a major handicap.”

Modular data centers, and specifically the containerized variety, were first introduced about 10 years ago when larger companies such as Google started using traditional container-sized units almost like “giant racks where they could ship in huge loads of servers at a time,” says Liz Cruz, associate director at IHS Markit. They were often used in more niche applications until over the past five years or so when more use cases opened up for temporary data center installations and even facilities used for disaster recovery.

Cruz points out that there is quite a bit of variety in terms of the sizes and functions of these containerized data centers, but that a large segment of the market is moving toward custom enclosures that are typically larger than shipping containers. At the same time, some vendors offer containers that are essentially closet-sized power systems designed for remote areas with little or no access to grid-based energy sources; Flexenclosure’s eSite containers are an example of this. And then you have products like those from BladeRoom where there are a series of separate container modules that can be essentially “ganged together to form what looks more like a traditional data center,” Cruz explains.

Baselayer Edge modules are specifically designed for HPC (high-performance computing) use cases and can be deployed both indoors and outdoors.

Potential Use Cases
Needless to say, there is a great deal of variety in the modular data center space, but that doesn’t mean you can find something for every possible use case. There is certainly a lot of potential in this market, but modular data centers must be used in the right situations and for the right reasons to be effective. For example, organizations such as the Red Cross are tasked with entering a region reeling from a recent disaster and setting up a temporary data center nearby so they have the resources needed to help; this is a perfect example of a situation in which a modular data center can be extraordinarily helpful. The same idea applies in the military, which may need to place a data center in a remote region for a couple of years rather than investing in a more permanent structure. But, in addition to these kinds of temporary installations, there are indeed more permanent use cases, especially in areas where space is limited.

“Some of the best examples are hospitals,” says Cruz. “The indoor space is at such a premium for the a hospital. Their building space could be used for beds for patients, which is revenue-generating. They don’t want to be using that space for a data center, which isn’t a revenue-generating endeavor for them,” but rather a necessary part of doing business. For hospitals, Cruz continues, “it makes more sense to put a data center out in the parking lot and spend a little bit more up front in order to free up that space indoors,” thereby saving indoor space for their primary business of serving patients.

As we’ve mentioned, containerized data centers aren’t for everyone, and Cruz will be the first to admit that “it’s unlikely someone who hasn’t thought about modular at this point is going to completely redo their data center architecture and turn it into a containerized data center. Still, there are other unique use cases that pop up from time to time to illustrate the versatility and importance of modular, containerized data centers.

One example is that of a man who purchased an old manufacturing facility in Chicago and wanted to retrofit it into a data center only to find out that he couldn’t maximize space utilization without being a bit creative. “There was a courtyard area where the walls were too low and he couldn’t put a roof over the courtyard because the historical society wouldn’t let him, so there was all of this wasted space that he couldn’t put a roof over, which he obviously needed to protect his servers,” says Cruz. “So, instead, he was just going to put some containerized data centers out there. A majority of the data center would be traditionally built, but there would be a few out there in the courtyard. This is another reason to just keep containerized in the back of your mind as an option because it might come into play sometime and be a useful solution.”

The BladeRoom modular data center is system is designed so that you can connect multiple modules to one another, whether they are meant to handle IT load or for cooling, and configure them so they look and operate similarly to a traditional data center.

Cruz notes that while there is so much potential and opportunity for growth in the modular and containerized data center market, the segment is never likely to make a huge dent in the overall data center market. In fact, by 2020, she doesn’t see modular data centers making up more than 3% of the overall data center install base. However, one of the reasons why the market is poised for high growth (aside from the fact that by virtue of being a small market, any growth could result in high percentage gains) is due to the growth of edge data centers in general.

Edge data centers are intended to be placed closer to customers in order to improve performance and user experience, but at the same time these data centers aren’t infrastructure powerhouses meant to handle an overabundant server load. Cruz says one of the drawbacks of containerized data centers is the inherent “discomfort of serviceability” because there isn’t much room to move around inside of them, but that doesn’t matter as much in an edge data center setting.

For an example of the usefulness of modular and containerized data centers, look no further than Pokemon Go. The creator of that app, Niantic, so greatly underestimated demand that when the game went online the company almost instantly encountered major server shortage issues. Because containerized data centers can be deployed so quickly almost anywhere, they could have been used in this scenario to help handle some of the load in the regions that needed it most. And that leads directly into another reason why the market is growing, especially when it comes to edge data centers, and why more vendors are jumping in.

“A lot of the building of edge data centers will be done by the telecommunication and network carriers, which have already been using containerized modular solutions for their network and telecommunications equipment,” says Cruz. “They weren’t containerized data centers. It was just shipments of modules with network and telco equipment, so companies like Emerson are trying to move more into the containerized data center side have a strong business already with network equipment so it’ll be a natural transition.”

Flexenclosure’s eSite hybrid power systems are designed for use in telecommunications and other industries where 100% network uptime is a must even in remote areas where access to grid-based power is challenging or unavailable.

Not Necessarily A Competitor To Cloud Or An Aid To Consolidation
You might be taking a look at containerized data centers and thinking maybe they would be a good solution for consolidation, or even for moving assets to the cloud, but that isn’t necessarily true. For one, containerized data centers are more expensive than traditional builds. “No supplier in good conscience can tell me that it’s ever going to get less or even competitively priced with a traditional build,” says Cruz. That’s a big factor, because if it’s more expensive, then it’s always going to be a major handicap.” And when it comes to the cloud, containerized data centers simply won’t help companies achieve the goals they have in mind with a typical cloud migration.

“In the way that we’re talking about modular data centers, I don’t think there’s really a competition with cloud,” says Cruz. “Cloud [involves] a company saying, ‘I’m going to outsource everything. I’m no longer going to own the servers or the infrastructure.’ They are basically completely outsourcing their data center management. They’re not looking to have anything to do with the operation of their data center anymore. With a containerized data center,” Cruz adds, “all you’ve outsourced is the design. Once it’s delivered to you, you still have to manage it just as you would a regular data center. I don’t think of cloud so much as a competitor for containerized data centers.”

And therein lies the limiting factor regarding growth in the modular data center market. More and more companies are moving toward colocation and cloud computing to get out of the internal infrastructure business, because many of them only got into the data center game because it was the only way for them to run the business in the past. Today, companies have more options than ever before when it comes to offerings via SaaS (software as a service), managed services, and cloud computing generally. And, in fact, that’s where much of the data center dollars will be going in the coming years.

“Most of the future data center building that we’re anticipating is coming from cloud and colocation builders, which benefit from economies scale,” says Cruz. “You lack that with containerized data centers, because you’re turning everything into a unit.” Cruz says “there are a few cases here and there” where colocation providers have adopted containerized data centers, “but it’s looking less like a regular solution for them. If these guys aren’t doing it, it’s not going to be the be all, end all.”

Still, Cruz projects growth up to 2.3% by 2020, and she sees more potential for growth in the future, even if it won’t ever top more than perhaps 5% of total data center IT load. This helps illustrate that while it may not be a huge market or even a major mainstream one, there is still a place for modular data centers and containerized data centers. As with any other technology, you simply have to look at the fundamentals of what you’re trying to achieve as a business and determine whether or not modular data centers fit into those plans.

Why Go Modular?

When you hear about modular data centers, your mind may not immediately go to prefabricated containers, but rather the general concept of modular design. The important thing to remember is that modular design is an overarching philosophy to building data centers that focuses on the ability to easily replace pieces of equipment and to scale up or scale down as necessary by essentially plugging new servers, storage solutions, and other systems into the facility as needed.

Liz Cruz, associate director with IHS Markit, says “you can’t argue that the mentality of building in a modular fashion is almost universally adopted now” and she doesn’t “think anyone would decide to build out an entire data center that they think will suit them for the next 20 years up front anymore.” But the same idea doesn’t necessarily apply to modular and containerized data centers, which often have highly specialized use cases and aren’t meant to be permanent data centers fixtures.

IoT and Smart City during my visit in Taiwan 29 March 2017 (3)

On 31 March, we visited Kaohsiung Software Park. They have 8 ha area, consist of 4 buildings that have some software company. They started the area just a view years ago, to keep maintain and support manufacture industry among Kaohsiung.

We visited Brogent Technology, an Entertainment related company. So many good products relate to entertainment, artificial intelligence technology.

We visited ELAN showroom to see IoT and Smart City related solutions.

We listened and discuss other IoT and Smart City solutions.

We saw a lot related solution of IoT and Smart City. Some of them already implemented and success.
I hope APTIKNAS and APKOMINDO can help them to introduce, and implement related solutions.

We also have ASISINDO with Smart City Center in Mangga Dua Square Jakarta that will open in May 2017 to cover, educate and exhibit smart city solutions.

see you again soon.

IoT and Smart City during my visit in Taiwan 29 March 2017 (2)

We moved to Kaohsiung, using Taiwan High Speed Train, 395 km within 1.5 hours.
Then we join the big event of 2017 TAIWAN INDONESIA INDUSTRIAL COLLABORATION  SUMMIT , and they are 5 areas, including ICT.

I think almost 200 people join this meeting.

After the plenary meeting, we entered our areas of meeting. This is our team. My self, Fanky Christian, Mr. Ashari Abidin, Mr. Andi Tanudiredja, and Mr. Ary Achmad Arman (ITB), and Mr. Soegiharto Santoso as team leader, he is also Chairman of APKOMINDO and APTIKNAS.

Although APTIKNAS (Asosiasi Pengusaha Teknologi Informasi & Komunikasi Nasional) or National ICT Businessman , we have the same structure with APKOMINDO. We have 25 sub regional agency throughout Indonesia which can help to implement, support IoT and Smart City implementations.

In the ICT forum, we discussed with great people, such as CTO Asus, President Tatung. Mr. Soegiharto Santoso (Hoky) highlighted some issue that we can collaborate together to achieve success together.

We have finalized 3 main issue to collaborate together. And APKOMINDO or APTIKNAS ready to support these issues. Also  Smart City Initiatives Indonesia will support these. We also have Mr. Andi (from Makasar City Gov) and Mr. Wahyudi (from BPJT) join the effort.

This is our picture on finalized collaboration together in the forum.

We have dinner together with all the members.

We do hope our collaboration will bring success to everyone.


IoT and Smart City during my visit in Taiwan 29 March 2017


We are having good time during my visit on Taipei, 28 March - 1 April 2017. I meet a lot of companies, presented their solutions to Indonesia. Most of them are IoT and Smart City related.

28 March 2017, this is my first trip to Taiwan. And I saw a lot new thing which related to IoT and Smart City. When we entered the city, we use high way, and I see a lot gates like this. And the good thing is, I don't see any payment gates likes used to be. They changed the way they do the payment.


In this gates, they are using laser to trigger the camera. The cars move under this gate and capture their license plate. They also capture the RFID ID. The RFID ID was passive RFID installed on the car's head lamp or mirror.

Then, we visited FETC, the company that run these facilites for Taiwan Gov. The people buy their payment using banks and their virtual account. Every time their car move in to highway, they will be capture. And they use different calculation, like we are trying to do in ERP. I think their approach is better, because they can measure exactly number of amount to deduct when the car move in the highway. If they cannot capture the RFID's car, and neither the capture license number, they have 3 places that consist of agent to review the capture images and check the correct by agent's eyes.

We visited their place like these, they have 30 agent to see the capture license images directly.

The chairman explaining the FETC in detail. And I think this is very good, but not easy to implement in Indonesia. We have another challenge, mind set and culture. ;)

We are visited ITRI's office at Taipei to meet some companies presented their IoT and Smart City solutions. Some of them related to IoT, Smart Health and Smart Learning.
