[Document Centralization - Together with Mr. Yoo] Ep 5. mcloudoc – Support of various kinds of network environments



- We will connect you with service product inquiries and consultation related to mcloudoc.



#1. Company network structure - Stand Alone
Shall we look at the first structure? This is a structure that is usually used by customer companies with less than 100 users. There is only one server. Employees access and use the server directly from their PCs.

#2. Company network structure - Active-Passive
Next is a structure that is mainly used by customer companies with 100~500 users. ClouDoc servers are configured in pairs like 2, 4, and 6 servers. Each server has a high availability (HA) solution installed.
Among the servers with high availability solutions installed, the Active servers are used for service. If there is a problem with this Active Server, the Passive Server becomes an Active Server to support the service.

# 3. Company network structure - Active-Active
Next is Active-Active. It is mainly used by customers with over 300 users. At least two servers and even up to tens of servers can be used. In this case, load balancing can be done between servers through L4 switching or Load Balancing Service (LBS). A High Availability (HA) solution is only required for database redundancy. ClouDoc is designed to enable Active-Active services without a separate solution. Because all participating servers are always running, server utilization is much higher than Active-Passive.

 #4. External document exchange server structure
The ClouDoc server is usually only accessible from the Intranet to prevent attacks by external malignant code. You can build an external document exchange server in the DMZ to securely exchange files with the outside. Employees can exchange files with the outside easily with Windows Explorer.

# 5. External DRM server structure
The external DRM server structure is the same as the external document exchange server structure. The only difference is that the file is encrypted when exported. Employees will encrypt the files in Windows Explorer after acquiring an approval from a team leader to send the files to the outside. Those who receive this document will provide non-repudiation and information leakage protection through security functions including One Time Password.

# 6. Access via VPN during business trip or working at home
 If you have traveled outside or need to work at home urgently, you can connect to the ClouDoc server via VPN to work. In some cases, you may connect from outside by using router settings or a virtual desktop program, although we don’t recommend this.

# 7. Access via Proxy server during business trip or working at home
ClouDoc provides connection via Proxy server for both PC and mobile devices. This feature is especially useful for accessing ClouDoc servers on smartphones. Unlike the VPN server, it is very useful because it can access the ClouDoc server from the outside only by setting it up without the need to install a separate program.

#8. Access to external ClouDoc server via Proxy server
ClouDoc's proxy server support was developed for when ClouDoc is outside, not on the Intranet. This feature can be very useful if all corporate Internet connections are only allowed through a proxy server.

# 9. Application to network separation environment
In a network separation environment, ClouDoc performs well through the external document exchange server and data exchange system between networks that exist in a DMZ. A data exchange system between networks is a data movement method used to block the inflow of malicious code between Internet and Intranet.
If you install an external DRM server instead of an external document exchange server in the DMZ, ClouDoc can perform well through the data exchange system between networks.
   
# 10. Collaborative use information leakage prevention collaboration environment
Let’s look at a work environment where you need to work with the partners, but you do not want the partner's products to leak. Partner employees connect to the VPN server. Next, they go through the proxy server and access the ClouDoc server in the Intranet through the data exchange system between networks.
In this environment, all of the deliverables will be stored on the ClouDoc server when the partner employees work.
ClouDoc's security policy is flexible. Depending on the IP band you connect to, you can apply different security policies, even if they are the same user. If a partner employee turns off the PC and reboots, he/she can deactivate the security policy if not connected to ClouDoc. In this way, security policies can be strengthened while ensuring the convenience of partner companies.
