Netdisk is an online storage service that provides file storage, access, backup, contribution and other functions. It is an indispensable service in our daily life. Many Internet companies provide free network disk services for individuals and businesses. However, these free services have some limitations, such as limiting download speed, limiting file size, not being able to be managed by multiple people at the same time, and not being able to implement some customized functions. If you want to remove these restrictions, you have to pay. Now I will introduce to you a free private network disk with unlimited functions. We can use the open source network disk software NextCloud: Nextcloud - Open source content collaboration platform , and cooperate with the free service quota provided by Amazon Cloud Technology to build a private network disk with no usage restrictions. The tutorial is very simple. The installation process only requires three lines of commands. I hope it can help you.
Cost advantage
Due to the wide variety of Amazon cloud technology services and detailed billing, many users cannot understand it, so they are deterred from using Amazon Cloud. In fact, many Amazon Cloud Technology services have free packages to allow users to experience them. The free packages of these services are more than enough to build a private network disk. Since Amazon Cloud Overseas Area only requires a personal credit card to register, we take the overseas area as an example. We can see which Amazon Cloud services have free packages from the following link : Amazon AWS overseas regional account free package_free cloud service-AWS cloud service:

- Returning to the EC2 service interface, we observe that the instance status is "Running" and the status check is "2 checks passed." It means it has been created successfully. Check the check box in front of the instance and click the "Connect" button on the right.
- We use EC2 Instance Connect to log in to the EC2 instance from the browser. If it fails, use the language switch in the lower left corner of the console interface to switch the console interface to English to solve this problem. However, some regions do not support EC2 Instance Connect. If you encounter a region that does not support EC2 Instance Connect, you can refer to the "Connect to an instance" section in the tutorial below: Start an EC2 Linux instance
- After logging in to the instance, first install the open source network disk software NextCloud and run the command:
sudo snap install nextcloud
- After the installation is completed, it will prompt "nextcloud 22.1.1snap2 from Nextcloud✓ installed". The software installation is complete. You need to configure the username and password. Use the following command, where xiayan is replaced by your username and passw0rd is replaced by your password:
sudo nextcloud.manual-install xiayan passw0rd
- After the configuration is completed, "Nextcloud was successfully installed" will be displayed. We now need to configure the trust domain. If you want to use IP to access the network disk, then after the following command "value=", you write the elastic IP you just configured. If you have your own domain name, you will use the domain name to access later, then the following Write your domain name after the command "value=", and point your domain name to the elastic IP just configured.
sudo nextcloud.occ config:system:set trusted_domains 1 --value=替换为您的 IP 地址或域名
- Now we can use a browser to open the IP address or domain name just now. Pay attention to using http. If the browser fails to open, you can try to enter the completed address, http:// plus the IP address. Log in with the username and password you just configured. However, the current interface is in English. You can click on the personal settings in the upper right corner to change the language to Chinese.
Operation Guide: Configure NextCloud backend storage as S3

in conclusion
At this point, the private network disk based on Graviton2 and S3 free packages has been successfully built. NextCloud has desktop, Android and iOS clients, which can be used for synchronization and backup. It also has a powerful multi-user system that can allow multiple people to work and share together, and can also be well integrated with WordPress, etc. This article is just an introduction, and there are many areas for improvement, such as configuring CloudFront CDN to accelerate network disk access. CloudFront also has a 50GB free package. You can also configure the network disk to https for more secure access. It is worth paying for a good product. According to this plan, even if the free package expires, the EC2 instance can be converted to an annual subscription for only 4.58USD per month, and the S3 storage only costs 0.023USD per GB per month.
