5 Keunggulan Teknologi SD-WAN

SD-WAN adalah singkatan dari software-defined wide area network yang merupakan jaringan area luas yang ditentukan perangkat lunak dan memanfaatkan komponen perangkat untuk mengontrol operasi jaringan. Perangkat lunak manajemen khusus memvirtualisasikan perangkat keras jaringan dengan cara yang sama seperti hypervisors dan komponen lain memvirtualisasikan operasi pusat data.

SD-WAN adalah sebuah teknik untuk menggunakan perangkat lunak untuk membuat jaringan area luas (wide area network) lebih cerdas dan fleksibel. Sebenarnya apa kegunaan dari SD-WAN ini? Menurut artikel yang dimuat di Technopedia, SD-WAN dapat membantu jaringan area luas untuk menangani lalu lintas jaringan dengan protokol tertentu, sambil menyediakan antarmuka yang intuitif bagi pengguna. Tidak hanya itu, SD-WAN juga dapat mendukung fitur seperti firewall, gateway, dan alat jaringan pribadi virtual untuk privasi. Selain itu, SD-WAN juga dapat membantu redundansi, per cadangan dan pemulihan, serta pemecahan masalah.

Kenapa SD-WAN ini penting? Dikarenakan SD-WAN dapat mengatasi masalah yang lumrah terjadi di IT organisasi seperti downtime yang dapat mempengaruhi reputasi dan garis bawah. Jika sudah begini, maka dibutuhkan solusi IT yang gesit, fleksibel, dan dapat menghemat biaya.

Dengan adanya SD-WAN, masalah tersebut di atas dapat diatasi dengan pendekatan baru yang juga membawa skala dan keamanan perusahaan. Itu sebabnya SD-WAN menjadi salah satu solusi jaringan paling populer yang tersedia saat ini.

Ada 5 Kelebihan atau keunggulan SD-WAN yang bisa didapatkan seperti berikut ini :

1. Biaya Konektifitas Lebih Rendah

Keunggulan pertama dari SD-WAN ini yaitu dapat mengurangi biaya operasional yang sedang berlangsung dengan beralih ke jalur MPLS (Multiprotocol Label Switching) yang mahal ke broadband komoditas seperti serat, kabel, DSL, atau bahkan teknologi seluler.

2. Performa Lebih Tinggi untuk Cloud

Keunggulan selanjutnya adalah dengan SD-WAN, jalur baru dapat ditambahkan dengan cepat dan mudah ke situs yang membutuhkan kapasitas yang lebih. Dengan menghubungkan situs-situs secara langsung ke internet, SD-WAN mengurangi hambatan dan penundaan yang umum terjadi pada WAN yang lebih lama.

3. Beberapa Ketahanan Tautan (Multiple Link Resilience)

Lingkungan WAN tradisional biasanya memiliki satu tautan jaringan yang masuk ke setiap lokasi. Dengan SD-WAN, banyak tautan dari ISP yang berbeda dapat digunakan, menghilangkan satu titik kegagalan yang dapat menjatuhkan jaringan.

4. Ketangkasan Lebih Tinggi

Ketika Anda membuka kantor cabang baru, waktu adalah uang. SD-WAN memungkinkan Anda untuk mengatur jaringan yang andal dan aman dengan cepat, menggunakan ISP mana saja yang paling sesuai untuk setiap lokasi.

5. Optimized Use of Resources

SD-WAN memungkinkan Anda untuk menetapkan aplikasi utama secara cerdas ke berbagai tautan, termasuk jalur internal dan koneksi Internet, memberikan jaminan Kualitas Layanan (QoS) yang berbeda untuk masing-masingnya. Ini memungkinkan Anda menerapkan sumber daya yang tepat dalam setiap situasi untuk memaksimalkan kinerja dan produktivitas sambil meminimalkan biaya.

“CDN Indonesia” For Better Website Performance

The best way to increase speed and reduce resource usage by a website is to use a Content Delivery Network. CDN is a technology that can ensure that your static content (such as images, CSS, JavaScript, video, etc.) can be accessed more quickly, by channeling it from the location closest to your visitors, thus increasing server response times. Content Delivery Networks can be used for large-scale websites, which have a lot of content.

However, in fact, all websites can still use it to improve website performance. Most CDN providers are paid but have many benefits. So, there is no reason not to use it. In this tutorial, you will learn what a “CDN Indonesia” is and how to use it for your website. What is a CDN? CDN is A content distribution network / content delivery network / CDN is a collection of global servers located in several data centers around the world that are responsible for distributing websites and all related website content.

Can the CDN be used in all hosting services?

The trick to increasing speed with a CDN is through a distributed network of servers that funnel files to the visitor from the location closest to the visitor. Maybe you think that if you have a powerful hosting service, such as a VPS or a dedicated server, the use of a CDN will not have a significant impact. However, it doesn’t matter how many resources you have, server location is also one of the biggest factors to increase website access speed from the visitor’s side. For example, you are from India, meanwhile, your website server is located in America.

Due to the long distance between the visitor location and the server location, content delivery can take quite a long time. CDN servers are usually placed in several places, for example, CDNs that are placed in India, America, Singapore, etc. If the visitor is from Indonesia, the CDN will serve the file from the location closest to the visitor (in this case, the CDN in India).

So, if you use a free web hosting service or shared hosting or VPS, a CDN will still help increase your website access speed, reduce disk space and bandwidth usage and ensure that your content is distributed quickly regardless of the distance between your website visitors and your hosting server. If you use a shared hosting service or free hosting, CDN will help you save resource usage, which will have a significant impact because generally resources are limited to such services.

If one day your website gets a surge in visitors, the CDN will ensure that this does not make you run out of resource limits. Using a CDN can help improve performance and speed across all hosting services. Benefits of a CDN The following are some of the benefits of a Content Delivery Network (CDN): CDNs are great for websites that have a lot of visitors CDN ensures that web pages can perform well all over the world By reducing the number of requests (data requests) to the server, CDN is able to minimize the use of your hosting resources (disk space / bandwidth, etc.)

Website access speed will be noticeably increased, especially if the visitor is located close enough to the server location Website ranking on Google can increase because the access speed factor is very much considered by Google A CDN can benefit many types of websites and web hosting

How Do We Stay Secure Online?

The Internet is a fantastic thing, but it has so many computers and devices connected leaves us vulnerable to a whole host of cybercrime and viruses. Fortunately, there are many ways to ensure you are protected.


I was concerned about being online-how do I stay safe?

Many people are concerned about their internet security, and with good reason. It is true that the Internet can be a source of many scams-and there are always horror stories in the newspapers about the virus infects machines and hackers from accessing personal information online.

So it would be easy to think that browsing the internet is a dangerous activity. But stay safe online is the same as staying safe anywhere- take proper precautions from the beginning, use your common sense, and you can protect yourself from the problem.

In the same way that you lock your house and close the windows when you go out, your computer needs some basic security to guard against intruders. As soon as you connect, you need to put some security systems. But do not think that you are on your own in trying to protect your device your ISP internet, data center services, computer manufacturers and software engineers continue to try to improve security, and automatically build safeguards to help you.

What do I need?

Your computer has three lines of defense (or should be). Each of these help keep your computer safe from attacks. Three systems are firewalls, antivirus software and operating system up-to-date.

First, what is a firewall?

If you are connected to the Internet via a home broadband router, it will almost certainly have some protective software called a firewall built in. When you’re online, you’re connected to another computer to access their services. In contrast, other computers on the internet access services can be served by your computer.

digital firewall acts as a barrier, blocking access to your computer unless you allow it. It is a bit like a nightclub bouncer, standing between your home computer and troublemakers net.
