Oracle Cloud's permanent free cloud servers have powerful performance and high configuration

As the world's leading cloud computing service provider, Oracle Cloud has launched a free cloud server plan that is considered the best in the industry. This service not only has amazing configurations, but also provides a unique resource combination in the field of free cloud services. This article will analyze the details of Oracle Cloud's free service in depth and provide a detailed application guide.

1. Analysis of the core configuration of Oracle Cloud free service

Oracle Cloud's free plan includes two core computing resources:

• AMD computing instance : Each account can create two virtual machines with 1/8 OCPU (equivalent to 0.125 vCPU) and 1GB of memory. Although the CPU resources are limited, they are sufficient for lightweight applications.
• ARM Ampere A1 Compute Instances : This is the real highlight, with up to four instances available, providing a total of 4 cores of CPU and 24GB of memory. Each instance is allocated a minimum of 47GB of storage, which means users can get a total of 188GB of high-performance storage.

In terms of storage, Oracle Cloud provides each account with a 200GB block storage quota, which users can freely allocate according to their needs. In terms of network resources, all free instances share 10TB of outbound traffic (inbound traffic is completely free), which is more than enough for most individual users and small businesses.

2. Other permanent free services

In addition to computing instances, Oracle Cloud also provides nearly 30 permanent free services:

• 20GB object storage (similar to AWS S3)
• Two 20GB Oracle Autonomous Databases
• Three 25GB NoSQL databases
• 5 volume backup
• Load Balancer
• Monitoring and alerting services
• Key Management Services

These services combined together form a complete cloud computing ecosystem, and users can build complex application architectures based on these free resources.

III. Key preparations before application

When applying for an Oracle Cloud free account, you need to pay special attention to the following points:

1. Payment card preparation

You must prepare an international bank card (Visa, MasterCard or American Express) that supports foreign currency consumption. Both credit cards and debit cards are fine, but the debit card needs to have enough balance in the account (it is recommended to reserve about US$3).

2. Account type selection

Oracle Cloud provides two types of registration: individual and corporate. If you have corporate qualifications, it is recommended to register with corporate identity because:

• The pass rate for enterprise users may be higher
• It will be more convenient to upgrade paid services in the future
• Resource quotas may be more relaxed

3. Information consistency principle

When applying, you must ensure that:

• The IP address is consistent with the geographical location filled in
• The bank card billing address is consistent with the registration information
• All personal information is true and valid

4. Network environment optimization

Since Oracle Cloud uses the hCaptcha verification system, China Mobile users may encounter the problem that the verification code cannot be displayed. Suggestions:

• Use China Telecom or China Unicom network
• Try using a mobile hotspot
• Avoid using proxies or VPNs

IV. Detailed application steps

Step 1: Visit the official website

Open the Oracle Cloud Free Plan page: https://www.oracle.com/cn/cloud/free

Step 2: Fill in basic information

Include country, name, email address, etc. Special attention:

• City/province/zip code must correspond

Step 7: Payment Verification

This is the most critical step:

1. Select "Credit Card" verification method
2. Fill in the complete bank card information
3. The billing address must be accurate
4. The system will pre-authorize about $1 for verification

Step 8: Complete the registration

After checking the service agreement, click "Start my free trial" to complete the registration.

5. Suggestions for handling failed applications

The Oracle Cloud application approval rate is low. If you encounter failure, you can try:

• Changing network environment (different ISP)
• Change payment card (it is recommended to use a card from a different bank)
• Modify registration information (name/address, etc.)
• Wait 1-2 weeks before trying again
• Consider purchasing a ready-made account (market price is about 200-500 yuan)

6. Things to note after success

After successful application, it is recommended to immediately:

1. Setting up account security: Enabling multi-factor authentication
2. Create resource limit alerts: Avoid unexpected charges
3. Back up important configurations to prevent loss due to accidental operation
4. Log in regularly: Avoid account recovery due to inactivity

7. Free resource usage suggestions

Reasonable use of Oracle Cloud free resources can build:

• Personal blog/website
• Development and testing environment
• Private Git repository
• VPN/Proxy Services
• Small database application
• Automation script server
