企业上云为什么是数字化转型升级的第一步
3月17日我们分享了一篇文章,”无企业,不上云”,被各大平台转载分享,这让我们看到了互联网的热情,也看到了企业对上云的渴望,艾锑无限作为阿里云的战略合作伙伴,我们更乐意帮助企业上云,让更多的企业迈向数字化时代.
我们相信每一家企业都是IT企业,每一家企业都是互联网企业,每一家企业都是数字化企业,这一切的基础都是基于云,云将会成为企业最重要的基础设施,就像水、媒、电一样的重要.IT外包
1、应变力
云端快速部署、自由扩展的优势，使网站、APP等应用上线、迭代更加灵活，提高了信息系统的运营效率。云以突出的应变能力，适应多变的企业信息化进程，降低试错成本，加快研发进度，增强企业创新的信心。
2、稳定性
云环境为企业业务创造了一个稳定、可靠的空间，使用户体验更好，客户满意度显著提升。互联网产品获得流量和用户粘性的核心是用户体验，在线用户流畅访问，便捷操作，才会有较高的市场占有率。
3、性价比
云计算优异的性价比，为企业信息化大幅降低了成本。使企业可以把更多的资金，投入到业务创新中。传统企业转型升级存在着大量的不确定性，低成本的云计算帮助企业消除了资金上的顾虑。
4、安全性
转型中的传统企业，因对网络环境不熟悉，担心网络攻击、数据泄露等安全问题。云计算服务商有专业的技术和高效的服务体系，帮助企业保护数据安全、规避安全风险和提供海量数据查询，企业可以专注于网站和应用程序，而不是基础设施。
5、扩展性
在企业信息化的成本结构中，购买硬件软件成本占比很高，而实际用于开发的支出就相应很低，并且耗费时间较长。如果完全基于云开架设IT系统，几个小时就可完成基本框架。如果业务增加，就是直接购买服务器，边际效益很低，采用云后，由于云计算的高扩展性，通过边际效益可实现成本下降。
solaris中添加删除磁盘和分区
如何在solaris中添加删除磁盘和分区建意你先看 IDE 和 SCSI 分配名称
以下例子是格式化 Primary IDE Master 硬盘
查看 IDE 和 SCSI 分配名称后，我们知道 Primary IDE Master 硬盘名称是c0d0。
请先行 Login 成为 root user
# drvconfig ( configure the /devices directory )
# disks ( creates /dev entries for hard disks attached to the system )
# format
Searching for disks...done
AVAILABLE DISK SELECTIONS:
0. c0d0
/pci@0,0/pci-ide@7,1/ide@0/cmdk@0,0
1. c1t6d0
/pci@0,0/pci9004,8178@f/sd@6,0
Specify disk (enter its number): 0 ( 因为 Primary IDE Master 硬盘名称是c0d0，所以选择 0 )
AVAILABLE DRIVE TYPES:
0. other
Specify disk type (enter its number):0
( 正常应该是 0. DEFAULT 1. other，通常应该选择DEFAULT，但是Solaris不明白我的硬盘是什么，所
以只有other可供选择。)
我的IDE HardDisk架构如下:-
( 可以从BIOS Auto Detect查出來，通常都有LBA,LARGE,AUTO三种选择，建意你使用Auto，因為不能大
过16Heads和不能大过63Sectoes )

现在打算把 /dev/rdsk/c0d0s0 mount 在 /mnt/newhd
# cd /mnt
# mkdir newhd
在 /etc/vfstab Auto mount 的设定
device to mount = /dev/dsk/c0d0s0
device to fsck = /dev/rdsk/c0d0s0
mount point = /mnt/newhd
FS type = ufs
fsck pass = 1
mount at boot = yes
mount options = -
# pico vfstab or vi vfstab
加入 /dev/dsk/c0d0s0 /dev/rdsk/c0d0s0 /mnt/newhd ufs 1 yes -
# mount /mnt/newhd
完成 !
