7.Technical specifications and costs (expected to be June 3, 2018)
We will configure the high-end specification server to support investors and DAPP developers to build products on the EOS platform.and make corresponding adjustment and expansion with consideration on EOS. IO network situation, requires from community members and other block producers.

A)Server Configuration:
We will run two nodes, a physical server for livenet and another cloud-based server on backup to maximize uptime and stability. We plan to develop open-source failover system cooperate with block producers , which enable automatic backup system when the primary system failure.

Master server
CPU: 24 vCPUs 48 GB Intel Xeon E5-2682v4 2.5 GHz
RAM: 96GB
SSD: EBS-only
Network: 1,000 Mbps
SSD: 4096GB

Backup server
CPU: 16 vCPUs Intel Xeon Platinum 8163 2.5 GHz
RAM: 32GB
SSD: EBS-only
Network: 1,000 Mbps
SSD: 1024GB

Estimated Monthly Cost: USD $800

8.Hardware expansion plan (budget after June 3, 2018)
We plan to maintain and expand the best hardware specifications,the cost almost be depend on the requirements of EOS network however, EOS Wenzhou will not be subject to any foreseeable infrastructure costs.
Base on the requirements of EOS future developing ,we will take positive cooperation with well-known database centre on domestic and overseas, build proprietary EOS data center, equip with rich data center resources, cooling and electricity capacity, parallel server configuration for demand expansion.At the same time complete a higher load balance, equip with higher bandwidth on elastically. we will take the DNS intelligent resolutions in proper time,and make achievement on the request response and calculation requirements of the millisecond level.

RAM : 4TB
SSD : 4TB
Network: 10 Gbps
Firewall - Throughput 7.4Gbps
Shared Storage EBS Storage
EBS IOPS
32,000 IOPS
Estimated Monthly Cost: USD $7000

(B)Shared Storage EBS Storage
SSD : 500 TB
EBS IOPS
32,000 IOPS

(C)Redundancy :
Redundant hardware on flexibility in case of problems and failures.

(D)Failover cluster :
Disaster recovery: The server will operate in a shared storage failover cluster configuration. and host this virtual machine failover cluster running a EOSIO block producer when a cluster node hardware failured,The data block would be created or complete node is immediately migrated to another cluster node to prevent downtime.

(E)Updates:
Makes our underlying operating system up-to-date and upgrades the infrastructure easier.we can migrate in real time when upgrade allocation
We will use 2 direct attached storage arrays to host our virtual machines,which provide us with storage redundancy when the entire storage fails. and will also be easier to expand future time.

(F)Load balancing
We will use managed load balancer to handle the requests from our block, with the development of EOS.IO, which also enable us adding to more infrastructure seamlessly.

(G)Cloud hosted backup node/producer
We will run a non-block producer on cloud server in case of unplanned downtime. And move block producer from non-block producer to ensure no downtime when primary block come back online.

(H)Monitor
We will designate persons monitor our hardware and software 24/7
